    2002-06-01

    Tonsillectomy has been performed by a number of techniques. This double blind randomized controlled study compares the technique of tissue coblation with bipolar dissection for the removal of tonsils in 10 adult patients with a history of chronic tonsillitis. A significant reduction in post-operative pain and more rapid healing of the tonsillar fossae were found in the side removed by tissue coblation. There were no episodes of primary or secondary haemorrhage on either side. This new technique for tonsil removal warrants further study.

    OBJECTIVE: To examine the efficacy and safety of short-term and long-term use of antidepres-sants in the treatment of bipolar disorder. DATA SOURCES:A literature search of randomized, double-blind, control ed trials published until December 2012 was performed using the PubMed, ISI Web of Science, Medline and Cochrane Central Register of Control ed Trials databases. The keywords“bipolar disorder, bipolar I disorder, bipolar II disorder, bipolar mania, bipolar depression, cyclothymia, mixed mania and depression, rapid cycling and bipolar disorder”, AND “antidepressant agent, antidepressive agents second-generation, antidepressive agents tricyclic, monoamine oxidase inhibitor, noradrenaline uptake in-hibitor, serotonin uptake inhibitor, and tricyclic antidepressant agent” were used. The studies that were listed in the reference list of the published papers but were not retrieved in the above-mentioned databases were supplemented. STUDY SELECTION: Studies selected were double-blind randomized control ed trials assessing the efficacy and safety of antidepressants in patients with bipolar disorder. Al participants were aged 18 years or older, and were diagnosed as having primary bipolar disorder. Antidepressants or antidepressants combined with mood stabilizers were used in experimental interventions. Placebos, mood stabilizers, antipsychotics and other antide pressants were used in the control interventions. Studies that were quasi-randomized studies, or used antidepressants in combination with antipsy-chotics in the experimental group were excluded. Al analyses were conducted using Review Man-ager 5.1 provided by the Cochrane Col aboration. MAIN OUTCOME MEASURES:The primary outcome was the response and switching to mania. The secondary outcomes included remission, discontinuation rate, and suicidality. RESULTS: Among 5 001 treatment studies published, 14 double-blind randomized control ed trials involving 1 244 patients were included in the meta

    In acute pancreatitis (AP) tumor necrosis factor-α mediates multi-organ failure; in animal models its blockade with pentoxifylline ameliorates AP. The efficacy of pentoxifylline in predicted severe AP (pSAP) was tested in a double-blinded, randomized, control trial. Twenty-eight patients with pSAP were randomized within 72 hours of diagnosis to pentoxifylline or placebo. Baseline characteristics were similar in both groups. The pentoxifylline group had fewer intensive care unit admissions and shorter intensive care unit and hospital stays of longer than 4 days (all P < .05). Patients receiving pentoxifylline had no adverse effects. Pentoxifylline within 72 hours of pSAP is safe; a larger study of pentoxifylline in AP is needed to confirm efficacy.

    Full Text Available Studies follow a hierarchy in terms of the quality of evidence that they can provide. Randomized double blind placebo control (RDBPC studies are considered the "gold standard" of epidemiologic studies. And the same is discussed at length in this paper taking example of a real journal article employing this study design to answer the research question; "Does once daily dose of Valacyclovir reduce the risk of transmission of genital herpes in a susceptible partner?" RDBPC studies remain the most convincing research design in which randomly assigning the intervention can eliminate the influence of unknown or immeasurable confounding variables that may otherwise lead to biased and incorrect estimate of treatment effect. Also, randomization eliminates confounding by baseline variables and blinding eliminates confounding by co-interventions, thus eliminating the possibility that the observed effects of intervention are due to differential use of other treatments. The best comparison is placebo control that allows participants, investigators and study staff to be blinded. The advantage of trial over an observational study is the ability to demonstrate causality. Hope, this will be useful to neophyte researchers to understand causal hierarchy when critically evaluating epidemiologic literature.

    This double-blind randomized controlled trial was conducted to evaluate whether use of acupuncture could initiate labor at term and thus reduce post-term induction. Between 2010 and 2011, a total of 80 women at 38 weeks of gestation or greater were randomized to acupuncture and sham acupuncture groups. Acupuncture points LI4, SP6 and BL67 were needled bilaterally. The primary outcome was initiation of labor. The time from acupuncture to delivery, mode of delivery, fetal and maternal outcome and Apgar scores were recorded. The trial is registered at irct.ir, number IRCT201111218151N1. Eighty women were randomized and 75 women completed the study procedure. Age, BMI, parity and gestational age were similar in both groups. Spontaneous labor was initiated in 94.7 % of acupuncture group and 89.2 % of sham acupuncture group (p = 0.430). There were no statistically significant difference between groups for time from enrollment to delivery (p = 0.06). According to this study, it seems that acupuncture was not effective in labor initiation compared to sham acupuncture.

    Full Text Available Background: In spite of the availability of multiple treatment options, viral warts are known for their persistence and recurrence, causing frustration to patients and treating physicians. Aims: To study the effectiveness and safety of autoinoculation as a treatment modality in cutaneous warts. Methods: A double-blind, placebo-controlled study was carried out. In the treatment group, full-thickness warty tissue was excised, minced and implanted in a small dermal pocket. In the control group, warty tissue was only excised and not implanted, though a dermal pocket was made. Patients were evaluated every four weeks with lesion counts. The procedure was repeated at 4 and 8 weeks. Response was assessed at each visit and at 12 weeks. Results: Forty-eight patients with cutaneous warts (male: female = 32:16 were randomized into autoinoculation and control groups. The number of warts at baseline was comparable in both groups (P = 0.293. Reduction in the number of warts was significantly more in the autoinoculation group (8.50 ± 13.88 than in the control group (10.04 ± 5.80 from 8 weeks onwards (P = 0.010. Complete resolution occurred only in the autoinoculation group, in 62.5% of cases. Adverse effects were seen in 11 patients, including infection of the donor site (5 cases, keloid formation (3 and hypopigmentation (3. Conclusion: Autoinoculation may be an effective therapeutic modality for cutaneous warts and two sessions may be required for optimum results.

    Acute alcohol withdrawal syndrome (AAWS) is encountered in patients presenting acutely to the Emergency Department (ED) and often requires pharmacologic management. We investigated whether a single dose of intravenous (i.v.) phenobarbital combined with a standardized lorazepam-based alcohol withdrawal protocol decreases intensive care unit (ICU) admission in ED patients with acute alcohol withdrawal. This was a prospective, randomized, double-blind, placebo-controlled study. Patients were randomized to receive either a single dose of i.v. phenobarbital (10 mg/kg in 100 mL normal saline) or placebo (100 mL normal saline). All patients were placed on the institutional symptom-guided lorazepam-based alcohol withdrawal protocol. The primary outcome was initial level of hospital admission (ICU vs. telemetry vs. floor ward). There were 198 patients enrolled in the study, and 102 met inclusion criteria for analysis. Fifty-one patients received phenobarbital and 51 received placebo. Baseline characteristics and severity were similar in both groups. Patients that received phenobarbital had fewer ICU admissions (8% vs. 25%, 95% confidence interval 4-32). There were no differences in adverse events. A single dose of i.v. phenobarbital combined with a symptom-guided lorazepam-based alcohol withdrawal protocol resulted in decreased ICU admission and did not cause increased adverse outcomes.

    The effects of actiponin was investigated, a heat-processed Gynostemma pentaphyllum extract, on body weight, fat loss, and metabolic markers of Korean participants in a 12-week, randomized, double-blind, placebo-controlled clinical trial. Obese participants (BMI ≥ 25 kg m(-2) and WHR ≥ 0.90 for male or WHR ≥ 0.85 for female) who had not been diagnosed with any disease and met the inclusion criteria were recruited for this study. The 80 subjects were randomly divided into actiponin (n = 40, 450 mg day(-1) ) and placebo (n = 40) groups. Outcomes included measurement of efficacy (abdominal fat distribution, anthropometric parameters, and blood lipid profiles) and safety (adverse events, laboratory test results, electrocardiogram data, and vital signs). During 12-week of actiponin supplementation, total abdominal fat area, body weight, body fat mass, percent body fat, and BMI were significantly decreased (P = 0.044, P < 0.05, P < 0.0001, P < 0.0001, and P < 0.05, respectively) in the actiponin group compared to the placebo group. No clinically significant changes in any safety parameter were observed. Our study revealed that actiponin is a potent antiobesity reagent that does not produce any significant adverse effects. These results suggest that actiponin supplementation may be effective for treating obese individuals. Copyright © 2013 The Obesity Society.

    A double-blind, randomized, placebo-controlled study was conducted to determine the effect of nifedipine on early renal allograft function when added to a triple therapy immunosuppression regime comprising low-dose cyclosporin (CsA), prednisolone and azathioprine. Fifty adult cadaveric renal allograft recipients were randomized to placebo (group P n = 17), nifedipine 10 mg preoperatively and 20 mg b.d. postoperatively for 48 h, followed by matching placebo for 3 months (group NS n = 16) or nifedipine 10 mg preoperatively and 20 mg b.d. postoperatively for 3 months (group NL n = 17). Donor and recipient exclusion criteria included recent calcium antagonist treatment. At 3 months after transplantation mean GFR adjusted for graft loss was significantly higher in group NL than in NS (mean +/- SD 61 +/- 28 versus 34 +/- 25 ml/min/1.73 m2; P nifedipine commenced preoperatively and continued for 3 months following transplantation has beneficial effects on early renal allograft function when incorporated as part of an immunotherapy regimen based on cyclosporin.

    To explore ancient Vedic medical techniques, one hundred and seventy-six subjects with arthritis participated in a controlled study through the non-pharmacologic approach known as the Maharishi Vedic Vibration Technology (MVVT). Using a double-blinded and randomized experimental design, the findings showed significant reductions of pain and stiffness, and improvement in range of motion in the study sample. One hundred percent relief of symptoms was the most commonly reported category of improvement due to treatment. For the group as a whole, differences in mean response of treatment and control conditions with respect to relief of pain, limitation of motion, and reduction in stiffness were highly significant: t values ranged from a low of 5.609 in stiffness to a high of 20.950 in pain, p = 0.000009 to <10-49 respectively. Analysis by sub-categories of peripheral arthritis, painful conditions of the spine, and rheumatoid arthritis likewise produced significant results. Mechanisms of action were proposed, drawing on Maharishi Vedic Science, developments in quantum field theory, and specifically the theories of chaos and self-organizing systems as they relate to physiological functioning. The instantaneous relief of pain and improvement in function in such a high proportion of subjects with chronic arthritis is unparalleled in modern medical science

    Introduction. The purpose of this trial was to evaluate the effect of pterostilbene on metabolic parameters. Methods. A prospective, randomized, double-blind, and placebo-controlled study that enrolled 80 patients with a total cholesterol ≥200 mg/dL and/or LDL ≥ 100 mg/dL. Subjects were divided into four groups: (1) pterostilbene 125 mg twice daily; (2) pterostilbene 50 mg twice daily; (3) pterostilbene 50 mg + grape extract (GE) 100 mg twice daily; (4) matching placebo twice daily for 6-8 weeks. Endpoints included lipids, blood pressure, and weight. Linear mixed models were used to examine and compare changes in parameters over time. Models were adjusted for age, gender, and race. Results. LDL increased with pterostilbene monotherapy (17.1 mg/dL; P = 0.001) which was not seen with GE combination (P = 0.47). Presence of a baseline cholesterol medication appeared to attenuate LDL effects. Both systolic (-7.8 mmHg; P < 0.01) and diastolic blood pressure (-7.3 mmHg; P < 0.001) were reduced with high dose pterostilbene. Patients not on cholesterol medication (n = 51) exhibited minor weight loss with pterostilbene (-0.62 kg/m(2); P = 0.012). Conclusion. Pterostilbene increases LDL and reduces blood pressure in adults. This trial is registered with Clinicaltrials.gov NCT01267227.

    Full Text Available To evaluate the impact of luteal phase support with vaginal progesterone on pregnancy rates in the intrauterine insemination (IUI cycles, stimulated with clomiphene citrate and human menopausal gonadotropin (hMG, in sub fertile couples.This prospective, randomized, double blind study was performed in a tertiary infertility center from March 2011 to January 2012. It consisted of 253 sub fertile couples undergoing ovarian stimulation for IUI cycles. They underwent ovarian stimulation with clomiphene citrate (100 mg and hMG (75 IU in preparation for the IUI cycle. Study group (n = 127 received luteal phase support in the form of vaginal progesterone (400 mg twice a day, and control group (n = 126 received placebo. Clinical pregnancy and abortion rates were assessed and compared between the two groups.The clinical pregnancy rate was not significantly higher for supported cycles than that for the unsupported ones (15.75% vs. 12.69%, p = 0.3. The abortion rate in the patients with progesterone luteal support compared to placebo group was not statistically different (10% vs. 18.75%, p = 0.45.It seems that luteal phase support with vaginal progesterone was not enhanced the success of IUI cycles outcomes, when clomiphene citrate and hMG were used for ovulation stimulation.

    Full Text Available Abstract Background Diarrhea causes an estimated 2.5 million child deaths in developing countries each year, 35% of which are due to acute diarrhea. Zinc and copper stores in the body are known to be depleted during acute diarrhea. Our objectives were to evaluate the efficacy of zinc and copper supplementation when given with standard treatment to children with acute watery or bloody diarrhea. Methods We conducted a double-blind randomized controlled clinical trial in the Department of Pediatrics at Indira Gandhi Government Medical College Nagpur, India. Eight hundred and eight children aged 6 months to 59 months with acute diarrhea were individually randomized to placebo (Pl, zinc (Zn only, and zinc and copper (Zn+Cu together with standard treatment for acute diarrhea. Results The mean duration of diarrhea from enrolment and the mean stool weight during hospital stay were 63.7 hours and 940 grams, respectively, and there were no significant differences in the adjusted means across treatment groups. Similarly, the adjusted means of the amount of oral rehydration solution or intravenous fluids used, the proportion of participants with diarrhea more than 7 days from onset, and the severity of diarrhea indicated by more than three episodes of some dehydration or any episode of severe dehydration after enrolment, did not differ across the three groups. Conclusion The expected beneficial effects of zinc supplementation for acute diarrhea were not observed. Therapeutic Zn or Zn and Cu supplementation may not have a universal beneficial impact on the duration of acute diarrhea in children.

    Fragile X syndrome (FXS), the most common cause of inherited intellectual disability and autistic spectrum disorder, is typically caused by transcriptional silencing of the X-linked FMR1 gene. Work in animal models has described altered synaptic plasticity, a result of the up-regulation of metabotropic glutamate receptor 5 (mGluR5)-mediated signaling, as a putative downstream effect. Post hoc analysis of a randomized, placebo-controlled, crossover phase 2 trial suggested that the selective mGluR5 antagonist mavoglurant improved behavioral symptoms in FXS patients with completely methylated FMR1 genes. We present the results of two phase 2b, multicenter, randomized, double-blind, placebo-controlled, parallel-group studies of mavoglurant in FXS, designed to confirm this result in adults (n = 175, aged 18 to 45 years) and adolescents (n = 139, aged 12 to 17 years). In both trials, participants were stratified by methylation status and randomized to receive mavoglurant (25, 50, or 100 mg twice daily) or placebo over 12 weeks. Neither of the studies achieved the primary efficacy end point of improvement on behavioral symptoms measured by the Aberrant Behavior Checklist-Community Edition using the FXS-specific algorithm (ABC-C(FX)) after 12 weeks of treatment with mavoglurant. The safety and tolerability profile of mavoglurant was as previously described, with few adverse events. Therefore, under the conditions of our study, we could not confirm the mGluR theory of FXS nor the ability of the methylation state of the FMR1 promoter to predict mavoglurant efficacy. Preclinical results suggest that future clinical trials might profitably explore initiating treatment in a younger population with longer treatment duration and longer placebo run-ins and identifying new markers to better assess behavioral and cognitive benefits.

    Background: Lowering cholesterol is associated with reduced CNS amyloid deposition and increased dietary cholesterol increases amyloid accumulation in animal studies. Epidemiologic data suggest that use of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) may decrease the risk of Alzheimer disease (AD) and a single-site trial suggested possible benefit in cognition with statin treatment in AD, supporting the hypothesis that statin therapy is useful in the treatment of AD. Objective: To determine if the lipid-lowering agent simvastatin slows the progression of symptoms in AD. Methods: This randomized, double-blind, placebo-controlled trial of simvastatin was conducted in individuals with mild to moderate AD and normal lipid levels. Participants were randomly assigned to receive simvastatin, 20 mg/day, for 6 weeks then 40 mg per day for the remainder of 18 months or identical placebo. The primary outcome was the rate of change in the Alzheimer's Disease Assessment Scale–cognitive portion (ADAS-Cog). Secondary outcomes measured clinical global change, cognition, function, and behavior. Results: A total of 406 individuals were randomized: 204 to simvastatin and 202 to placebo. Simvastatin lowered lipid levels but had no effect on change in ADAS-Cog score or the secondary outcome measures. There was no evidence of increased adverse events with simvastatin treatment. Conclusion: Simvastatin had no benefit on the progression of symptoms in individuals with mild to moderate AD despite significant lowering of cholesterol. Classification of evidence: This study provides Class I evidence that simvastatin 40 mg/day does not slow decline on the ADAS-Cog. PMID:21795660

    Having good balance is a facilitating factor in the performance of everyday activities. Good balance is also essential in various sport activities in order to both get results and prevent injury. A common measure of balance is postural sway, which can be measured both antero-posteriorly and medio-laterally. There are several companies marketing wristbands whose intended function is to improve balance, strength and flexibility. Randomized controlled trials have shown that wristbands with holograms have no effect on balance but studies on wristbands with minerals seem to be lacking. The aim of this study was to investigate if the mineral wristband had any effect on postural sway in a group of healthy individuals. Randomized, controlled, double-blind study. The study group consisted of 40 healthy persons. Postural sway was measured antero-posteriorly and medio-laterally on a force plate, to compare: the mineral wristband, a placebo wristband, and without any wristband. The measurements were performed for 30 s, in four situations: with open eyes and closed eyes, standing on a firm surface and on foam. Analyses were made with multilevel technique. The use of wristband with or without minerals did not alter postural sway. Closed eyes and standing on foam both prolonged the dependent measurement, irrespective if it was medio-lateral or antero-posterior. Wearing any wristband (mineral or placebo) gave a small (0.22-0.36 mm/s) but not statistically significant reduction of postural sway compared to not wearing wristband. This study showed no effect on postural sway by using the mineral wristband, compared with a placebo wristband or no wristband. Wearing any wristband at all (mineral or placebo) gave a small but not statistically significant reduction in postural sway, probably caused by sensory input.

    The aim of this study was to determine whether 3 days of TENS therapy postoperatively after shoulder operations would result in better pain relief and/or reduced analgesic intake when compared to placebo. The study was carried out randomized, double-blind and placebo controlled. Thirty patients were randomized to two groups. The verum group received TENS SM1AKS 80 Hz 6 mA and the placebo group received TENS SM1AKS 80 Hz 0 mA. The pain was assessed pre-operatively using the Hamburg Pain Adjective List. Premedication and Anaesthesia were standardized. TENS was applied to the patients immediately postoperatively for 8 hours and then on the following days 5 times daily for 45 minutes. The effectiveness was evaluated postoperatively using a visual analogue scale (rest, activity), the Hamburg Pain Adjective List and postoperative analgesic consumption. The visual analogue scale at rest and on activity showed no significant difference between the groups. Postoperative analgesic consumption of morphine hydrochloride in the first 24 hours was at time 8 hours postoperative significantly and at all other time points markedly less in the verum group compared to the placebo group. The sensory secondary scale score of the "Hamburg Pain Adjective List" was significantly lower postoperatively compared to preoperatively in the verum group. We were able to show in this study that TENS applied postoperatively after shoulder surgery clearly reduced analgesic consumption in the first 72 hours. Furthermore there was a significant difference in the pain scores using the "Hamburg Pain Adjective List" in favour of the verum group. TENS applied postoperatively is a effective, simple modality with few side-effects.

    Full Text Available Abstract Background Epidemiological studies suggest that smokeless tobacco in the form of Swedish snus has been used by many smokers in Scandinavia to quit smoking, but the efficacy of snus has so far not been evaluated in controlled clinical trials. Methods We conducted a randomized, double-blind, placebo-controlled, clinical trial aimed at assessing the efficacy of snus to help adult cigarette smokers in Serbia to substantially reduce, and, eventually, completely stop smoking. The study enrolled 319 healthy smokers aged 20-65 years at two occupational health centers in Belgrade, Serbia. Most of them (81% expressed an interest to quit rather than just reduce their smoking. Study products were used ad libitum throughout the 48-week study period. The main study objective during the first 24 weeks was smoking reduction. The primary end-point was defined as a biologically verified reduction of ≥ 50% in the average number of smoked cigarettes per day during week 21-24 compared to baseline. During week 25-48 participants were actively instructed to stop smoking completely. Outcome measures of biologically verified, complete smoking cessation included 1-week point prevalence rates at clinical visits after 12, 24, 36, and 48 weeks, as well as 4-, 12- and 24-week continued cessation rates at the week 36 and 48 visits. Results At the week 24 visit, the proportion of participants who achieved the protocol definition of a ≥ 50% smoking reduction was similar in the two treatment groups. However, the proportion that reported more extreme reductions (≥ 75% was statistically significantly higher in the snus group than in the placebo group (p Conclusions Swedish snus could promote smoking cessation among smokers in Serbia, that is, in a cultural setting without traditional use of oral, smokeless tobacco.

    The lidocaine patch 5% was developed to treat postherpetic neuralgia. Anecdotal experience at our institution suggests the lidocaine patch 5% decreases narcotic usage in patients with traumatic rib fractures. This trial was developed to define the patch's efficacy. Patients with rib fractures admitted to the trauma service at our Level I trauma center were enrolled and randomized in a 1 to 1 double-blind manner to receive a lidocaine patch 5% or placebo patch. Fifty-eight patients who met the inclusion criteria were enrolled from January 2007 to August 2008. Demographic and clinical information were recorded. The primary outcomes variable was total narcotic use, analyzed using the 1-tailed Mann-Whitney test. The secondary outcomes variables included non-narcotic pain medication, average pain score, pulmonary complications, and length of stay. Significance was defined based on a 1-sided test for the primary outcome and 2-sided tests for other comparisons, at p rib fractures, gender, trauma mechanism, preinjury lung disease, smoking history, percent of current smokers, and need for placement of chest tube between the lidocaine patch 5% and placebo groups. There was no difference between the lidocaine patch 5% and placebo groups, respectively, with regard to total IV narcotic usage: median, 0.23 units versus 0.26 units; total oral narcotics: median, 4 units versus 7 units; pain score: 5.6 +/- 0.4 versus 6.0 +/- 0.3 (mean +/- SEM); length of stay: 7.8 +/- 1.1 versus 6.2 +/- 0.7; or percentage of patients with pulmonary complications: 72.7% versus 72.0%. The lidocaine patch 5% does not significantly improve pain control in polytrauma patients with traumatic rib fractures.

    Full Text Available Abstract Background Studies of the efficacy of vitamin C treatment for fatigue have yielded inconsistent results. One of the reasons for this inconsistency could be the difference in delivery routes. Therefore, we planned a clinical trial with intravenous vitamin C administration. Methods We evaluated the effect of intravenous vitamin C on fatigue in office workers. A group of 141 healthy volunteers, aged 20 to 49 years participated in this randomized, double-blind, controlled clinical trial. The trial group received 10 grams of vitamin C with normal saline intravenously, while the placebo group received normal saline only. Since vitamin C is a well-known antioxidant, oxidative stress was measured. Fatigue score, oxidative stress, and plasma vitamin C levels were measured before intervention, and again two hours and one day after intervention. Adverse events were monitored. Results The fatigue scores measured at two hours after intervention and one day after intervention were significantly different between the two groups (p = 0.004; fatigue scores decreased in the vitamin C group after two hours and remained lower for one day. Trial also led to higher plasma vitamin C levels and lower oxidative stress compared to the placebo group (p Conclusion Thus, intravenous vitamin C reduced fatigue at two hours, and the effect persisted for one day. There were no significant differences in adverse events between two groups. High dose intravenous vitamin C proved to be safe and effective against fatigue in this study.

    Full Text Available Abstract Background Amenorrhea is defined as the cessation of menses. Hormone therapy is the most common treatment. Due to the contraindications and side effects of it and the increasing demand for alternative medicine substitutes, Mentha longifolia L. was used in this study. Mentha longifolia L. is a known medication in Iranian traditional medicine to induce menstrual bleeding in women with secondary amenorrhea and oligomenorrhea. Methods A double-blind, randomized, placebo-controlled, multicenter study was conducted in 120 women with secondary amenorrhea and oligomenorrhea. Treatment consisted of sequential oral syrup, 45 ml (15 ml three times a day for 2 weeks. If the patients did not have menstruation after 2 weeks of taking the medication, we would wait for two more weeks. If the patients had menstruation at each stage of using the drug, we started it one week after the end of menstruation. But if the patients had not menstruate after four weeks (two-week using of drug and waiting for two more weeks, the previous steps were repeated. The drug and placebo were repeated in three cycles of menstruation. Bleeding was documented by the patient on diary cards. The primary outcome variable was the occurrence (yes/no of bleeding during the first treatment cycle. The secondary efficacy outcome was the regularity of bleeding pattern during the three cycles of the study. Results The number of women with bleeding during the first cycle were higher in the drug group as in the placebo group (68.3% vs. 13.6%; p Mentha longifolia L. syrup. Conclusion In conclusion, Mentha longifolia L. syrup is a safe, well-tolerated, and effective choice in inducing bleeding and maintaining regular bleeding in women with secondary amenorrhea and oligomenorrhea.

    Background Acetaminophen (APAP, paracetamol) mechanism for analgesic and antipyretic outcomes has been largely addressed, but APAP action on cognitive function has not been studied in humans. Animal studies have suggested an improved cognitive performance but the link with analgesic and antipyretic modes of action is incomplete. This study aims at exploring cognitive tests in healthy volunteers in the context of antinociception and temperature regulation. A double-blind randomized controlled study (NCT01390467) was carried out from May 30, 2011 to July 12, 2011. Methods Forty healthy volunteers were included and analyzed. Nociceptive thresholds, core temperature (body temperature), and a battery of cognitive tests were recorded before and after oral APAP (2 g) or placebo: Information sampling task for predecisional processing, Stockings of Cambridge for spatial memory, reaction time, delayed matching of sample, and pattern recognition memory tests. Analysis of variance for repeated measures adapted to crossover design was performed and a two-tailed type I error was fixed at 5%. Results APAP improved information sampling task (diminution of the number of errors, latency to open boxes, and increased number of opened boxes; all P<0.05). Spatial planning and working memory initial thinking time were decreased (P=0.04). All other tests were not modified by APAP. APAP had an antinociceptive effect (P<0.01) and body temperature did not change. Conclusion This study shows for the first time that APAP sharpens decision making and planning strategy in healthy volunteers and that cognitive performance and antinociception are independent of APAP effect on thermogenesis. We suggest that cognitive performance mirrors the analgesic rather than thermic cascade of events, with possibly a central role for serotonergic and cannabinoid systems that need to be explored further in the context of pain and cognition.

    Full Text Available Abstract Background Colorectal cancer is one of the major neoplasms and a leading cause of cancer death worldwide, and new preventive strategies are needed to lower the burden of this disease. Metformin, a biguanide, which is widely used for treating diabetes mellitus, has recently been suggestive to have a suppressive effect on tumorigenesis and cancer cell growth. In a previous study conducted in non-diabetic subjects, we showed that oral short-term low-dose metformin suppressed the development of colorectal aberrant crypt foci (ACF. ACF have been considered as a useful surrogate biomarker of CRC, although the biological significance of these lesions remains controversial. We devised a prospective randomized controlled trial to evaluate the chemopreventive effect of metformin against metachronous colorectal polyps and the safety of this drug in non-diabetic post-polypectomy patients. Methods/Design This study is a multi-center, double-blind, placebo-controlled, randomized controlled trial to be conducted in non-diabetic patients with a recent history of undergoing colorectal polypectomy. All adult patients visiting the Yokohama City University hospital or affiliated hospitals for polypectomy shall be recruited for the study. Eligible patients will then be allocated randomly into either one of two groups: the metformin group and the placebo group. Patients in the metformin group shall receive oral metformin at 250 mg per day, and those in the placebo group shall receive an oral placebo tablet. At the end of 1 year of administration of metformin/placebo, colonoscopy will be performed to evaluate the polyp formation. Discussion This is the first study proposed to explore the effect of metformin against colorectal polyp formation. Metformin activates AMPK, which inhibits the mammalian target of rapamycin (mTOR pathway. The mTOR pathway plays an important role in the cellular protein translational machinery and cell proliferation. Patients with

    Full Text Available Mucoactive drugs should increase the ability to expectorate sputum and, ideally, have anti-inflammatory properties. The aim of the study was to evaluate the mucolytic activity of Tyloxapol compared to saline (0.9% in COPD.A randomized, placebo-controlled, double-blinded crossover, clinical trial was carried out. Patients were randomly assigned to either inhale 5 ml Tyloxapol 1% or saline 0.9% solution three times daily for 3 weeks and vice versa for another 3 weeks. 28 patients (18 male, 10 female, 47 to 73 years old, median age 63.50 were screened, 21 were treated and 19 patients completed the study per protocol.A comparison of the two treatment phases showed that the primary endpoint sputum weight was statistically significant higher when patients inhaled Tyloxapol (mean 4.03 g, 95% CI: 2.34-5.73 g at week 3 compared to saline (mean 2.63 g, 95% CI: 1.73-3.53 g at week 3. The p-value at three weeks of treatment was 0.041 between treatment arms. Sputum cells decreased during the Tyloxapol treatment after 3 weeks, indicating that Tyloxapol might have some anti-neutrophilic properties. Lung function parameters (FVC, FEV1, RV, and RV/TLC remained stable during the study, and no treatment effect was shown. Interestingly, there was a mean increase in all inflammatory cytokines (IL-1β, IL-6, and IL-8 during the saline treatment from day 1 to week 3, whereas during the Tyloxapol treatment, all cytokines decreased. Due to the small sample size and the large individual variation in sputum cytokines, these differences were not significant. However, analyses confirmed that Tyloxapol has significant anti-inflammatory properties in vitro. Despite the high number of inhalations (more than 1000, only 27 adverse events (20 during the Tyloxapol and seven during saline were recorded. Eleven patients experienced AEs under Tyloxapol and six under saline treatment, which indicates that inhalation of saline or Tyloxapol is a very safe procedure.Our study

    AIM: To evaluate the effectiveness of paracetamol as a prophylactic analgesic for hysterosalpingography (HSG). DESIGN: A prospective double blind randomized controlled trial comparing one 1 g of paracetamol (SmithKline Beecham, Brentford, U.K.) to placebo taken 30 min before HSG. One hundred consecutive out-patients were studied prospectively. The analgesic effectiveness during the procedure and at 24 h and 1 week post procedure was analysed by a postal pain score questionnaire. Additional data on the ethnicity of the patient, sex and level of experience of the radiologist performing the hysterosalpingogram, the parity of the patient, the ease of the procedure, and whether pathology was identified were also recorded. RESULTS: Eighty-eight patients (88%) replied, 39 (44%) received paracetamol and 49 placebo (56%). During the procedure 3/39 (7%) of women in the paracetamol group were pain-free compared to 9/49 (18%) in the placebo group, which was not significant (P = 0.11). At 24 h, 15/39 (38%) of women in the paracetamol group were pain-free compared to 20/49 (41%) in the placebo group, which was not significant (P = 0.82). At 1 week, 27/39 (69%) of women in the paracetamol group were pain-free compared to 29/49 (59%) in the placebo group, which was not significant (P = 0.33). No significant difference in mean pain scores was determined during the procedure (P 0.91), or at 24 h post procedure (P = 0.94). Similarly, no difference in mean pain scores was identified with regard to the ethnicity of the patient, the sex of the radiologist performing the procedure, the level of experience of the radiologist performing the procedure, or whether pathology was present or not. Difficult cannulations were associated with higher mean pain scores, however, there was no difference in mean pain scores between the paracetamol or placebo groups for both easy and difficult cannulations. CONCLUSION: Paracetamol is not effective as a prophylactic analgesic for HSG. If a prophylactic

    Halitosis (bad breath) is a common condition that is socially crippling for vast parts of the population and results from malodorous volatile sulfur compounds, which are by-products of oral bacteria. In this doubled-blind, randomized study, 75 subjects with halitosis were evaluated. The participants were treated with or without abrasive microcapsules (candy) containing zinc gluconate 0.5%, propolis 2%, and a combination of both (zinc 0.25% and propolis 1%). The halitosis was assessed by a Halimeter, a portable instrument that measures the emission of volatile sulfur compounds at different time exposures to the treatments. Breezy candy (which is sugar-free) was found effective in the treatment of halitosis for up to 4 hours. While treatment with regular candy (group 1, traditional candy without abrasive particles) showed reduction in malodor of 10%, Breezy candy showed reduction of up to 60% in malodor (P halitosis. The combined effect of abrasion by microcapsules with zinc supplement represents a novel and successful approach for the treatment of halitosis.

    Residual symptoms of major depressive disorder are a source of long-term morbidity. New therapeutic strategies are required to alleviate this morbidity and enhance patient quality of life. Citicoline has been used for vascular accidents and has been effective in cognitive rehabilitation. It has been used successfully to reduce craving in patients with substance abuse disorder and for mood management of bipolar disorder. Here, we test citicoline effectiveness as an adjuvant therapy in major depression. A double-blind randomized trial was designed on 50 patients with major depressive disorder who were under treatment with citalopram. Patients were allocated to 2 groups and received citicoline (100 mg twice a day) or placebo as an adjuvant treatment for 6 weeks. Depressive symptoms were assessed by the Hamilton Depression Rating Scale (HDRS) at baseline and at weeks 2, 4, and 6. Significantly greater improvement was observed in the HDRS scores of the citicoline group compared with the placebo group from baseline to weeks 2, 4, and 6 (Ps = 0.030, 0.032, and 0.021, respectively). Repeated-measures general linear model demonstrated a significant effect for time × treatment interaction on the HDRS score (F2.10,101.22 = 3.12, P = 0.04). Remission rate was significantly higher in the citicoline group compared with the placebo group (P = 0.045). Citicoline was an effective adjuvant to citalopram in the therapy of major depressive disorder.

    The objective of the study was to evaluate the effects of probiotic supplementation on the gut microbiota profile and inflammatory markers in chronic kidney disease patients undergoing maintenance hemodialysis (HD). This was a randomized, double-blind, placebo-controlled study. Forty-six HD patients were assigned to receive 1 of 2 treatments: probiotic (n = 23; Streptococcus thermophilus, Lactobacillus acidophilus e Bifidobacterialongum, 90 billion colony-forming units per day) or placebo (n = 23) daily for 3 months. Blood and feces were collected at baseline and after intervention. The inflammatory markers (C-reactive protein and interleukin-6) were analyzed by immunoenzymatic assay (enzyme-linked immunosorbent assay). Uremic toxins plasma levels (indoxyl sulfate, p-cresyl sulfate, and indole-3-acetic acid) were obtained by Reversed-Phase High-Performance Liquid Chromatography. Routine laboratory parameters were measured by standard techniques. Fecal pH was measured by the colorimetric method, and the gut microbiota profile was assessed by Denaturing Gradient Gel Electrophoresis analysis. Sixteen patients remained in the probiotic group (11 men, 53.6 ± 11.0 year old, 25.3 ± 4.6 kg/m(2)) and 17 in the placebo group (10 men, 50.3 ± 8.5 year old, 25.2 ± 5.7 kg/m(2)). After probiotic supplementation there was a significant increase in serum urea (from 149.6 ± 34.2 mg/dL to 172.6 ± 45.0 mg/dL, P = .02), potassium (from 4.4 ± 0.4 mmol/L to 4.8 ± 0.4 mmol/L, P = .02), and indoxyl sulfate (from 31.2 ± 15.9 to 36.5 ± 15.0 mg/dL, P = .02). The fecal pH was reduced from 7.2 ± 0.8 to 6.5 ± 0.5 (P = .01). These parameters did not change significantly in placebo group. Changes in the percentage delta (Δ) between groups were exhibited with no statistical differences observed. The inflammatory markers and gut profile were not altered by supplementation. Aprobiotic supplementation failed to reduce uremic toxins and

    A four-week, double-blind, randomized, placebo-controlled trial was conducted to assay the effectiveness of Ajwain 10 % (Trachyspermum ammi Sprague) topical cream on neuropathic pain. Intervention encompassed Ajwain 10 % and placebo creams. Ninety-two patients who specifically mentioned daily and nocturnal burning feet were randomly assigned to receive one of those interventions. Presence and decline in patients' numbness, tingling and allodynia were also evaluated. Major outcome measure was alteration in feet burning intensity (final week versus baseline week) regarding to a visual analog scale on a 0-10 cm scale (0 being "no pain", 10 being "worst pain"). Significant reduction in feet burning scores as well as numbness, tingling and allodynia were found in Ajwain group compared to placebo. This trial examining a cream of Ajwain essential oil versus placebo revealed the significance difference between two groups. This medicament can be a good candidate for the alleviation of feet burning, a neuropathic complication.

    This double-blind, randomized controlled study was conducted with the aim to investigate the effect of magnetic field therapy applied to the hip region on clinical and functional status in ankylosing spondylitis (AS) patients. Patients with AS (n = 66) who were diagnosed according to modified New York criteria were enrolled in this study. Patients were randomly divided in two groups. Participants were randomly assigned to receive magnetic field therapy (2 Hz) (n = 35), or placebo magnetic field therapy (n = 31) each hip region for 20 min. Patients in each group were given heat pack and short-wave treatments applied to bilateral hip regions. Both groups had articular range of motion and stretching exercises and strengthening exercises for surrounding muscles for the hip region as well as breathing and postural exercises by the same physical therapist. These treatment protocols were continued for a total of 15 sessions (1 session per day), and patients were examined by the same physician at months 1, 3 and 6. Visual analogue scale (VAS) pain, VAS fatigue, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Metrologic Index (BASMI), DFI, Harris hip assessment index and Ankylosing Spondylitis Quality of Life scale (ASQOL) were obtained at the beginning of therapy and at month 1, month 3 and month 6 for each patient. There were no significant differences between groups in the VAS pain, VAS fatigue, morning stiffness, BASDAI, BASFI, BASMI, DFI, Harris hip assessment index and ASQoL at baseline, month 1, month 3 or month 6 (p > 0.05). Further randomized, double-blind controlled studies are needed in order to establish the evidence level for the efficacy of modalities with known analgesic and anti-inflammatory action such as magnetotherapy, particularly in rheumatic disorders associated with chronic pain.

    Full Text Available OBJECTIVE To evaluate the efficacy of Calendula officinalis in relation to Essential Fatty Acids for the prevention and treatment of radiodermatitis. METHOD This is a randomized double-blind controlled clinical trial with 51 patients with head and neck cancer in radiotherapy treatment divided into two groups: control (27 and experimental (24. RESULTS There is statistically significant evidence (p-value = 0.0120 that the proportion of radiodermatitis grade 2 in Essential Fatty Acids group is higher than Calendula group. Through the Kaplan-Meier survival curve we observed that Essential Fatty Acids group has always remained below the Calendula group survival curve, due to the lower risk of developing radiodermatitis grade 1, which makes the usage of Calendula more effective, with statistical significance (p-value = 0.00402. CONCLUSION Calendula showed better therapeutic response than the Essential Fatty Acids in the prevention and treatment of radiodermatitis. Brazilian Registry of Clinical Trials: RBR-237v4b.

    In adults, mild traumatic brain injury (MTBI) frequently results in impairments of cognitive functions which would lead to psychological consequences in the future. Cerebrolysin is a nootropic drug, and can significantly improve cognitive function in patients with Alzheimer's disease and stroke. The purpose of this study was to investigate how Cerebrolysin therapy enhances cognitive recovery for mild traumatic brain injury patients using a double-blinded, placebo-controlled, randomized phase II pilot study. Patients having head injury within 24 h sent to our hospital were screened and recruited if patients were alert and conscious, and had intracranial contusion haemorrhage. From July 2009 to June 2010, totally, thirty-two patients were recruited in the double-blinded, placebo-controlled, and randomized study. Patients were randomized to receive Cerebrolysin (Group A, once daily intravenous infusion of 30 mL Cerebrolysin over a 60-min period for 5 days) or placebo (Group B, same dosage and administration of normal saline as Group A). The primary outcome measures were differences of cognitive function including Mini-Mental Status Examination (MMSE), and Cognitive Abilities Screening Instrument (CASI) scores between baseline and week 1, between baseline and week 4, and between baseline and week 12. Thirty-two patients completed the trial. For Group A, the CASI score difference between baseline and week 12 was 21.0 ± 20.4, a significantly greater change than that of Group B (7.6 ± 12.1) (p = 0.0461). Besides, drawing function (one of the domains of CASI; p = 0.0066) on week 4 and both drawing function (p = 0.0472) and long-term memory (one of the domains of CASI; p = 0.0256) on week 12 were also found to be significantly improved in the patients receiving Cerebrolysin treatment. Our results suggest that Cerebrolysin improves the cognitive function of the MTBI in patients at 3rd month after injury, especially for long-term memory and drawing function.

    Spirulina may increase people's ability to resist mental and physical fatigue. This study tested that hypothesis in a randomized, double blinded, placebo controlled study in men. After 1 week, a 3 g/day dose of spirulina produced a small, but statistically significant increase in exercise output (Kcals consumed in 30 min exercise on a cross trainer machine). A mathematical based mental fatigue test showed improved performance 4 h after the first time of supplementation as well as 8 weeks later. Similarly, a subjective survey for a sense of physical and mental fatigue showed improvement within 4 h of the first supplementation as well as 8 weeks later. These results show that spirulina intake can affect fatigue in men.

    The objective of this study was to determine the relative efficacy of irradiation using a device containing a far-infrared emitting ceramic powder (cFIR) for the management of chronic myofascial neck pain compared with a control treatment. This was a randomized, double-blind, placebo-controlled pilot study. The study comprised 48 patients with chronic, myofascial neck pain. Patients were randomly assigned to the experimental group or the control (sham-treatment) group. The patients in the experimental group wore a cFIR neck device for 1 week, and the control group wore an inert neck device for 1 week. Quantitative measurements based on a visual analogue scale (VAS) scoring of pain, a sleep quality assessment, pressure-pain threshold (PPT) testing, muscle tone and compliance analysis, and skin temperature analysis were obtained. Both the experimental and control groups demonstrated significant improvement in pain scores. However, no statistically significant difference in the pain scores was observed between the experimental and control groups. Significant decreases in muscle stiffness in the upper regions of the trapezius muscles were reported in the experimental group after 1 week of treatment. Short-term treatment using the cFIR neck device partly reduced muscle stiffness. Although the differences in the VAS and PPT scores for the experimental and control groups were not statistically significant, the improvement in muscle stiffness in the experimental group warrants further investigation of the long-term effects of cFIR treatment for pain management.

    Propolis contains a variety of chemical compounds, including polyphenols, flavonoids, phenolic aldehydes, amino acids and vitamins, and presents numerous biological and pharmacological properties. The aim of the present study was to evaluate the effect of propolis on blood examination data in patients with type 2 diabetes. In the double-blind, 8-week randomized controlled study, 80 patients with type 2 diabetes were enrolled. Patients were randomly assigned to receive Brazilian green propolis (226.8 mg/day for 8 weeks) (n=41) or the placebo (n=39). The primary endpoint was to detect changes in blood examination data associated with metabolic disorders in patients suffering from diabetes mellitus, including the homeostasis model assessment of insulin resistance (HOMA-IR), uric acid and estimated glomerular filtration rate (eGFR) from baseline to the end of this study. The value of HOMA-IR was not significantly changed by the 8-week administration of propolis or placebo from the baseline data. Values of blood uric acid and eGFR in patients taking the placebo became worse at 8 weeks compared to the baseline, whereas this did not occur in patients consuming Brazilian green propolis. However, HOMA-IR was not improved by propolis intake. A randomized, controlled 8-week trial suggests that Brazilian green propolis (226.8 mg/day) prevents patients with type 2 diabetes from developing worse blood uric acid and eGFR. PMID:26137235

The outcome measure were effect of cardiac function, Chinese medicine (CM) syndromes, scores of symptoms, signs, and quality of life measured by Minnesota Living with heart failure questionnaire (MLHFQ) before and after the treatment. Totally 112 patients were analyzed in the treatment group and 109 in the control group. They were comparable in NYHA functional class, basic parameters and primary diseases before treatment. Cardiac function and CM syndromes were greatly ameliorated in both groups after treatment. Total effective rates of cardiac function and CM syndrome in the treatment group were significantly higher than those in the control group (Pgasp, cough with phlegm, pulmonary rales and jugular vein engorgement between the two groups (P0.05). There was no obvious adverse reaction in either group noted during the study. Yangxinkang tablets were safe and efficacious in improving cardiac function, CM syndromes, symptoms, signs, and quality of life in patients with CHF class II or III in stage C on the base of conventional treatment.

Sibutramine 10 mg or placebo once a day. Main outcome measures: Body weight, routine laboratory and clinical safety monitoring.Results Of 233 eligible patients, 120 received sibutramine and 113 received placebo. Weight reduction was significantly greater in the intervened group (6.8±3.1) kg than the placebo control group (0.48±2.6) kg from week 4 onwards to week 24 (P<0.001). Some minor side effects were noticed in the subjects who took sibutramine. But the symptoms were light and short term. Sibutramine was will tolerated.Conclusions Sibutramine 10*!mg once a day is an effective an safe therapy for weight reduction in simple over-weighted and obese subjects.

    Full Text Available Abstract Background The scaphoid bone is the most commonly fractured of the carpal bones. In the Netherlands 90% of all carpal fractures is a fracture of the scaphoid bone. The scaphoid has an essential role in functionality of the wrist, acting as a pivot. Complications in healing can result in poor functional outcome. The scaphoid fracture is a troublesome fracture and failure of treatment can result in avascular necrosis (up to 40%, non-union (5-21% and early osteo-arthritis (up to 32% which may seriously impair wrist function. Impaired consolidation of scaphoid fractures results in longer immobilization and more days lost at work with significant psychosocial and financial consequences. Initially Pulsed Electromagnetic Fields was used in the treatment of tibial pseudoarthrosis and non-union. More recently there is evidence that physical forces can also be used in the treatment of fresh fractures, showing accelerated healing by 30% and 71% reduction in nonunion within 12 weeks after initiation of therapy. Until now no double blind randomized, placebo controlled trial has been conducted to investigate the effect of this treatment on the healing of fresh fractures of the scaphoid. Methods/Design This is a multi center, prospective, double blind, placebo controlled, randomized trial. Study population consists of all patients with unilateral acute scaphoid fracture. Pregnant women, patients having a life supporting implanted electronic device, patients with additional fractures of wrist, carpal or metacarpal bones and pre-existing impairment in wrist function are excluded. The scaphoid fracture is diagnosed by a combination of physical and radiographic examination (CT-scanning. Proven scaphoid fractures are treated with cast immobilization and a small Pulsed Electromagnetic Fields bone growth stimulating device placed on the cast. Half of the devices will be disabled at random in the factory. Study parameters are clinical consolidation

    It has been indicated that rotator cuff tears, especially large or massive ones, can cause suprascapular neuropathy. When such a diagnosis has been established, it is still unknown whether an arthroscopic release of the superior transverse scapular ligament during cuff repair can change the course of this neuropathy. This is a single-center, double-blinded randomized controlled trial for which 42 patients with large or massive repairable rotator cuff tears and suprascapular neuropathy will be recruited and followed up at 6 and 12 months. Nerve function will be measured by nerve conduction and electromyography studies preoperatively and at the selected follow-up periods. Patients will be randomly divided into equally numbered groups, the first one being the control group. Patients of this group will undergo arthroscopic repair of the rotator cuff without combined arthroscopic release of the superior transverse scapular ligament; in the second group the ligament will be released. The primary objective is to test the null hypothesis that arthroscopic repair of large/massive rotator cuff tears in patients with combined suprascapular neuropathy provides equivalent outcomes to one-stage arthroscopic cuff repair where the superior suprascapular ligament is additionally released. The secondary objective is to search for a relation between rotator cuff tear size and degree of suprascapular nerve recovery. The tertiary objective is to demonstrate any relation between rotator cuff muscle fatty infiltration grade and degree of suprascapular nerve function. Patients, clinicians during follow-up clinics and the neurologist will be blinded to the type of surgery performed. To the best of our knowledge, we are unaware of any prospective, randomized double-blinded studies with similar objectives. So far, the evidence suggests a positive correlation between massive rotator cuff tears and suprascapular neuropathy. However, there is mixed evidence suggesting that neuropathy can be

    Our previous studies have shown that mangiferin decreased serum triglycerides and free fatty acids (FFAs) by increasing FFAs oxidation in both animal and cell experiments. This study sought to evaluate the effects of mangiferin on serum lipid profiles in overweight patients with hyperlipidemia. Overweight patients with hyperlipidemia (serum triglyceride ≥ 1.70 mmol/L, and total cholesterol ≥ 5.2 mmol/L) were included in this double-blind randomized controlled trial. Participants were randomly allocated to groups, either receiving mangiferin (150 mg/day) or identical placebo for 12 weeks. The lipid profile and serum levels of mangiferin, glucose, L-carnitine, β-hydroxybutyrate, and acetoacetate were determined at baseline and 12 weeks. A total of 97 participants completed the trial. Compared with the placebo control, mangiferin supplementation significantly decreased the serum levels of triglycerides and FFAs, and insulin resistance index. Mangiferin supplementation also significantly increased the serum levels of mangiferin, high-density lipoprotein cholesterol, L-carnitine, β-hydroxybutyrate, and acetoacetate, and increased lipoprotein lipase activity. However, there were no differences in the serum levels of total cholesterol, low-density lipoprotein cholesterol, serum glucose, and insulin between groups. Mangiferin supplementation could improve serum lipid profiles by reducing serum triglycerides and FFAs in overweight patients with hyperlipidemia, partly due to the promotion of FFAs oxidation.

    Muscle damage induced by unaccustomed or eccentric exercise results in delayed onset vascular stiffening. We tested the hypothesis that a 7-day supplementation of panax ginseng and salvia miltiorrhiza prior to an acute eccentric exercise could attenuate arterial stiffening. By using a double-blind study placebo-controlled randomized design, subjects were randomly assigned to either the Chinese herb (N = 12) or the placebo group (N = 11) and performed a downhill running (eccentric exercise) trial and a control (seated rest) trial. Muscle soreness increased 1-2 days after exercise similarly in both groups, whereas the herb group demonstrated a faster recovery on active range of motion. Plasma creatine kinase concentration increased significantly at 24 h in both groups but the magnitude of increase was attenuated in the herb group. Arterial stiffness as measured by carotid-femoral pulse wave velocity increased significantly at 24 h in the placebo group but such increase was absent in the herb group. Flow-mediated dilation did not change in either group. Plasma concentrations of CRP and IL-6 increased in the placebo group but no such increases were observed in the herb group. Changes in arterial stiffness induced by eccentric exercise were associated with the corresponding changes in IL-6 (r = 0.46, P exercise. ClinicalTrials.gov: NCT02007304. Registered Dec. 5, 2013).

    Full Text Available BACKGROUND: Most patients with facial scarring would value even a slight improvement in scar quality. Botulinum toxin A is widely used to alleviate facial dynamic rhytides but is also believed to improve scar quality by reducing wound tension during healing. The main objective was to assess the effect of Botulinum toxin on scars resultant from standardized upper lip wounds. METHODS: In this double-blinded, randomized, vehicle-controlled, prospective clinical trial, 60 consecutive consenting adults undergoing cleft lip scar revision (CLSR surgery between July 2010 and March 2012 were randomized to receive botulinum toxin A (n = 30 or vehicle (normal saline; n = 30 injections into the subjacent orbicularis oris muscle immediately after wound closure. Scars were independently assessed at 6-months follow-up in blinded fashion using: Vancouver Scar Scale (VSS, Visual Analogue Scale (VAS and photographic plus ultrasound measurements of scar widths. RESULTS: 58 patients completed the trial. All scar assessment modalities revealed statistically significantly better scars in the experimental than the vehicle-control group. CONCLUSION: Quality of surgical upper lip scars, which are oriented perpendicular to the direction of pull of the underlying orbicularis oris muscle, is significantly improved by its temporary paralysis during wound healing.

    In spite of the availability of multiple treatment options, viral warts are known for their persistence and recurrence, causing frustration to patients and treating physicians. To study the effectiveness and safety of autoinoculation as a treatment modality in cutaneous warts. A double-blind, placebo-controlled study was carried out. In the treatment group, full-thickness warty tissue was excised, minced and implanted in a small dermal pocket. In the control group, warty tissue was only excised and not implanted, though a dermal pocket was made. Patients were evaluated every four weeks with lesion counts. The procedure was repeated at 4 and 8 weeks. Response was assessed at each visit and at 12 weeks. Forty-eight patients with cutaneous warts (male: female=32:16) were randomized into autoinoculation and control groups. The number of warts at baseline was comparable in both groups (P=0.293). Reduction in the number of warts was significantly more in the autoinoculation group (8.50±13.88) than in the control group (10.04±5.80) from 8 weeks onwards (P=0.010). Complete resolution occurred only in the autoinoculation group, in 62.5% of cases. Adverse effects were seen in 11 patients, including infection of the donor site (5 cases), keloid formation (3) and hypopigmentation (3). Autoinoculation may be an effective therapeutic modality for cutaneous warts and two sessions may be required for optimum results.

    Higher levels of serum uric acid are independently associated with endothelial dysfunction, a mechanism for incident hypertension. Overweight/obese individuals are more prone to endothelial dysfunction than their lean counterparts. However, the effect of lowering serum uric acid on endothelial dysfunction in these individuals has not been examined thoroughly. In this randomized, double-blind, placebo-controlled trial of nonhypertensive, overweight, or obese individuals with higher serum uric acid (body mass index ≥25 kg/m(2) and serum uric acid ≥5.0 mg/dL), we assigned subjects to probenecid (500-1000 mg/d), allopurinol (300-600 mg/d), or matching placebo. The primary outcome was endothelium-dependent vasodilation measured by brachial artery ultrasound at baseline and 8 weeks. By the end of the trial, 47, 49, and 53 participants had been allocated to receive probenecid, allopurinol, and placebo, respectively. Mean serum uric acid levels significantly decreased in the probenecid (from 6.1 to 3.5 mg/dL) and allopurinol groups (from 6.1 to 2.9 mg/dL) but not in the placebo group (6.1 to 5.6 mg/dL). None of the interventions produced any significant change in endothelium-dependent vasodilation (probenecid, 7.4±5.1% at baseline and 8.3±5.1% at 8 weeks; allopurinol, 7.6±6.0% at baseline and 6.2±4.8% at 8 weeks; and placebo, 6.5±3.8% at baseline and 7.1±4.9% at 8 weeks). In this randomized, double-blind, placebo-controlled trial, uric acid lowering did not affect endothelial function in overweight or obese nonhypertensive individuals. These data do not support the hypothesis that uric acid is causally related to endothelial dysfunction, a potential mechanism for development of hypertension. © 2016 American Heart Association, Inc.

    1Shivering is frequent during the post-anaesthetic recovery period, and there is no clear consensus about the best strategy for its treatment. We tested the efficacy of two commonly used analgesic drugs, pethidine and metamizol. 2A randomized, double-blind, placebo-controlled clinical trial was performed, including 104 adult patients who presented with post-anaesthetic shivering during the recovery from general anaesthesia. They were randomized to receive placebo (n=32), metamizol 25 mg kg−1 (n=37), or pethidine 0.4 mg kg−1 (n=35). The response to treatment was assessed 5, 15 and 45 min after drug administration, and the main outcome variable was complete suppression of shivering. 3The efficacy at 5, 15 and 45 min was as follows: placebo 6%, 16% and 37%; metamizol 13.5%, 32% and 76%, and pethidine 89%, 91% and 89%. With both active drugs the efficacy at all three time intervals was significantly higher than that with placebo (Pmetamizol were statistically significant (Pmetamizol produces a better post-anaesthetic shivering response than placebo, especially 15 and 45 min after drug administration; the efficacy of pethidine was the highest and the response to it appeared more quickly; however, at 45 min it was similar to that observed with metamizol. 5Both metamizol and pethidine suppress postanaesthetic shivering, but the latter induces a quicker and more reliable response.

Participants diagnosed with H. pylori infection were randomly assigned to two groups to orally receive 150 mg of GutGard (n=55 or placebo (n=52 once daily for 60 days. H. pylori infection was assessed using 13C-urea breath test (13C-UBT at days 0, 30, and 60. Stool Antigen test (HpSA was also performed on days 0, 30, and 60. Repeated measures of analysis of variance (RMANOVA, chi-square, and Fisher's exact probability tests were used to compare the treatment outcomes. A significant interaction effect between group and time (P=0.00 and significant difference in mean Delta Over Baseline (DOB values between GutGard (n=50 and placebo (n=50 treated groups after intervention period were observed. On day 60, the results of HpSA test were negative in 28 subjects (56% in GutGard treated group whereas in placebo treated group only 2 subjects (4% showed negative response; the difference between the groups was statistically significant. On day 60, the results of 13C-UBT were negative in 24 (48% in GutGard treated group and the difference between the groups was statistically significant. The findings suggest GutGard is effective in the management of H. pylori.

    Background. We for the first time examined the effects of a multiherb formula containing Crataegus pinnatifida (1 g daily), Alisma orientalis, Stigma maydis, Ganoderma lucidum, Polygonum multiflorum, and Morus alba on plasma lipid and glucose levels in Chinese patients with dyslipidemia. Methods. In this randomized, double-blind, placebo-controlled study, 42 patients were randomized at a ratio of 1 : 1 to receive the herbal formula or placebo for 12 weeks and 40 patients completed the study. Lipid profiles, glucose, glycated haemoglobin (HbA1c), and laboratory safety parameters were performed before and after treatment. Results. The difference in the changes in low-density lipoprotein cholesterol (LDL-C) levels between placebo and active treatment (-9%) was significantly (P < 0.05) better with active treatment. HbA1c levels significantly decreased by -3.9% in the active treatment group, but the change was not significantly different from that with placebo (-1.1%) (P = 0.098). There were no apparent adverse effects or changes in laboratory safety parameters with either treatment. Conclusions. The multiherb formula had mild beneficial effects on plasma LDL-C after 12-weeks treatment in subjects with dyslipidemia without any noticeable adverse effects.

    This study was designed to compare the therapeutic effects of topical clotrimazole and systemic fluconazole in pityriasis versicolor. A double-blind randomized controlled trial was carried out in the dermatological clinic of Gorgan, northern Iran, between April 2006 and May 2007. All consecutive patients with pityriasis versicolor were included and randomly divided into two groups. In the first group (G1), patients underwent treatment with a single dose of fluconazole capsule (400 mg) and placebo cream. In the second group (G2), patients underwent treatment with clotrimazole cream (twice daily) and placebo capsule. The course of treatment was 2 weeks. All subjects were re-evaluated 2, 4 and 12 weeks after the end of the therapeutic course. After 2 weeks, the rate of complete resolution of disease was significantly higher in G2 than G1 (49.1% vs 30%). After 4 weeks, 41 patients (81.2%) of G1 and 52 patients (94.9%) of G2 showed complete resolution. After 12 weeks, 46 patients (92%) in G1 and 45 patients (81.8%) in G2 showed complete resolution. Recurrence rate in G1 and G2 were 6% and 18.2%, respectively. No complications were seen in either group. In this study, clinical response at week 4 was greater in the clotrimazole group than the fluconazole group. Recurrence at week 12 after treatment was less with oral fluconazole than clotrimazole cream. So, for better evaluation, more studies need to be done.

    The existence of non-celiac gluten sensitivity has been debated. Indeed, the intestinal and extra-intestinal symptoms of many patients with irritable bowel syndrome (IBS) but without celiac disease or wheat allergy have been shown to improve on a gluten-free diet. Therefore, this study set out to evaluate the effects of gluten on IBS symptoms. We performed a double-blind randomized placebo-controlled rechallenge trial in a tertiary care hospital with IBS patients who fulfilled the Rome III criteria. Patients with celiac disease and wheat allergy were appropriately excluded. The participants were administered a gluten-free diet for 4 weeks and were asked to complete a symptom-based questionnaire to assess their overall symptoms, abdominal pain, bloating, wind, and tiredness on the visual analog scale (0-100) at the baseline and every week thereafter. The participants who showed improvement were randomly assigned to one of two groups to receive either a placebo (gluten-free breads) or gluten (whole cereal breads) as a rechallenge for the next 4 weeks. In line with the protocol analysis, 60 patients completed the study. The overall symptom score on the visual analog scale was significantly different between the two groups (Pgluten intervention group scored significantly higher in terms of abdominal pain, bloating, and tiredness (Pgluten diet may worsen the symptoms of IBS patients. Therefore, some form of gluten sensitivity other than celiac disease exists in some of them, and patients with IBS may benefit from gluten restrictions.

    The role of cholinergic abnormalities in autism was recently evidenced and there is a growing interest in cholinergic modulation, emerging for targeting autistic symptoms. Galantamine is an acetylcholinesterase inhibitor and an allosteric potentiator of nicotinic receptors. This study aimed to evaluate the possible effects of galantamine as an augmentative therapy to risperidone, in autistic children. In this randomized, double-blind, placebo-controlled, parallel-group study, 40 outpatients aged 4-12 years whom had a diagnosis of autism (DSM IV-TR) and a score of 12 or higher on the Aberrant Behavior Checklist-Community (ABC-C) Irritability subscale were equally randomized to receive either galantamine (up to 24 mg/day) or placebo, in addition to risperidone (up to 2 mg/day), for 10 weeks. We rated participants by ABC-C and a side effects checklist, at baseline and at weeks 5 and 10. By the study endpoint, the galantamine-treated patients showed significantly greater improvement in the Irritability (P = 0.017) and Lethargy/Social Withdrawal (P = 0.005) subscales than the placebo group. The difference between the two groups in the frequency of side effects was not significant. In conclusion, galantamine augmentation was shown to be a relatively effective and safe augmentative strategy for alleviating some of the autism-related symptoms.

    Full Text Available Purpose. This trial was performed to investigate the efficacy of laser acupuncture for the alleviation of lower back pain. Methods. This was a randomized, placebo-controlled, double-blind trial. Fifty-six participants were randomly assigned to either the laser acupuncture group (n=28 or the sham laser acupuncture group (n=28. Participants in both groups received three treatment sessions over the course of one week. Thirteen acupuncture points were selected. The visual analogue scale for pain, pressure pain threshold, Patient Global Impression of Change, and Euro-Quality-of-Life Five Dimensions questionnaire (Korean version were used to evaluate the effect of laser acupuncture treatment on lower back pain. Results. There were no significant differences in any outcome between the two groups, although the participants in both groups showed a significant improvement in each assessed parameter relative to the baseline values. Conclusion. Although there was no significant difference in outcomes between the two groups, the results suggest that laser acupuncture can provide effective pain alleviation and can be considered an option for relief from lower back pain. Further studies using long-term intervention, a larger sample size, and rigorous methodology are required to clarify the effect of laser acupuncture on lower back pain.

    Full Text Available Several different plant extracts have been evaluated with respect to their antimicrobial effects against oral pathogens and for reduction of gingivitis. Given that a large number of these substances have been associated with significant side effects that contraindicate their long-term use, new compounds need to be tested. The aim of this study was to assess the short-term safety and efficacy of a Lippia sidoides ("alecrim pimenta"-based essential oil mouthrinse on gingival inflammation and bacterial plaque. Fifty-five patients were enrolled into a pilot, double-blinded, randomized, parallel-armed study. Patients were randomly assigned to undergo a 7-day treatment regimen with either the L. sidoides-based mouthrinse or 0.12% chlorhexidine mouthrinse. The results demonstrated decreased plaque index, gingival index and gingival bleeding index scores at 7 days, as compared to baseline. There was no statistically significance difference (p>0.05 between test and control groups for any of the clinical parameters assessed throughout the study. Adverse events were mild and transient. The findings of this study demonstrated that the L. sidoides-based mouthrinse was safe and efficacious in reducing bacterial plaque and gingival inflammation.

    to investigate the efficacy and safety of a medicated plaster containing betamethasone valerate (BMV) 2.25 mg in patients with chronic elbow tendinopathy. randomized, double-blind, placebo-controlled study with assignment 2:2:1:1 to BMV medicated plaster applied daily for 12 hours, daily for 24 hours or matched placebo. 62 patients aged ≥18 years with chronic lateral elbow tendinopathy were randomized. The primary efficacy variable was pain reduction (VAS) at day 28. Secondary objectives included summed pain intensity differences (SPID), overall treatment efficacy and tolerability. mean reduction in VAS pain score at day 28 was greater in both BMV medicated plaster groups, -39.35±27.69 mm for BMV12-h and -36.91±32.50 mm for BMV24-h, than with placebo, -20.20±27.32 mm. Considering the adjusted mean decreases, there was a statistically significant difference between BMV12-h and placebo (p=0.0110). Global pain relief (SPID) and overall treatment efficacy were significantly better with BMV. BMV and placebo plasters had similar local tolerability and there were few treatment-related adverse events. BMV plaster was significantly more effective than placebo at reducing pain in patients with chronic elbow tendinopathies. The BMV plaster was safe and well tolerated.

    Pityriasis rosea is an acute self-limiting skin disorder of unknown aetiology. Recently human herpes virus 6 and 7 has been hypothesized to be the cause of pityriasis rosea. To determine the efficacy of acyclovir, an anti-viral drug, in the treatment of pityriasis rosea. A randomized, double-blind, placebo-controlled study of efficacy of oral acyclovir in the treatment of pityriasis rosea was conducted on 73 patients. Thirty eight randomly selected patients were started on oral acyclovir. Thirty-five patients were prescribed placebo. The patients as well as the chief investigator were unaware of the therapeutic group to which patients belonged (acyclovir or placebo). Patients in both the groups were evaluated clinically after 7 and 14 days following the first visit and the data were analysed. Follow up data of 60 patients was available and these were included in the statistical analysis. 53.33% and 86.66% of the patients belonging to the acyclovir group showed complete resolution on the 7(th) day and 14(th) day respectively following the first visit compared to 10% and 33.33% of patients from the placebo group. The findings were statistically significant. The study showed that high dose acyclovir is effective in the treatment of pityriasis rosea.

    Chlorophyll c2 extracted from Sargassum horneri improved allergic symptoms in an animal model of allergic rhinitis. In the present study, we explored the efficacy of chlorophyll c2 in patients with seasonal allergic rhinitis. This was a single-center, randomized, double-blind placebo-controlled trial. Sixty-six patients aged 20-43 years, each with a 2-year history of seasonal allergic rhinitis, were randomly assigned to receive either a single daily dose (0.7 mg) of chlorophyll c2 or placebo for 12 weeks. The use of medications including H1-antihistamines and topical nasal steroids was recorded by rescue medication scores (RMSs) noted after 4, 8, and 12 weeks of treatment. Disease-specific quality of life was measured using the Japan Rhinitis Quality of Life Questionnaire (JRQLQ) both before and after 4, 8, and 12 weeks of treatment. The RMS at 8 weeks was significantly better in the chlorophyll c2 than the placebo group (mean RMS difference = -3.09; 95 % confidence interval = -5.96 to -0.22); the mean RMS at 4 weeks was only slightly better in the chlorophyll c2 group. The JRQLQ scores did not differ significantly between the two groups. Chlorophyll c2 would have a potential to be an alternative treatment for allergic rhinitis.

    Background. We for the first time examined the effects of a multiherb formula containing Crataegus pinnatifida (1 g daily), Alisma orientalis, Stigma maydis, Ganoderma lucidum, Polygonum multiflorum, and Morus alba on plasma lipid and glucose levels in Chinese patients with dyslipidemia. Methods. In this randomized, double-blind, placebo-controlled study, 42 patients were randomized at a ratio of 1 : 1 to receive the herbal formula or placebo for 12 weeks and 40 patients completed the study. Lipid profiles, glucose, glycated haemoglobin (HbA1c), and laboratory safety parameters were performed before and after treatment. Results. The difference in the changes in low-density lipoprotein cholesterol (LDL-C) levels between placebo and active treatment (−9%) was significantly (P < 0.05) better with active treatment. HbA1c levels significantly decreased by −3.9% in the active treatment group, but the change was not significantly different from that with placebo (−1.1%) (P = 0.098). There were no apparent adverse effects or changes in laboratory safety parameters with either treatment. Conclusions. The multiherb formula had mild beneficial effects on plasma LDL-C after 12-weeks treatment in subjects with dyslipidemia without any noticeable adverse effects. PMID:24834096

    A decreased rate of successful helicobacter pylori (H.pylori) infection treatment has revealed serious demand for more effective regimens to eradicate infection. Therefore, probiotics have recently been considered to increase the rate of antibiotic regimens efficacy in H. pylori infections. In current randomized controlled trial, we evaluated the effect of double strain probiotic combination with standard triple therapy (STT), in the eradication rate of H. pylori infection. In current randomized placebo-control study, all patients (176 subjects) underwent the STT for 10 days. However, the study group received triple therapy for the eradication of H. pylori with supplement of Lactobacillus probiotic for 4 weeks and placebo was administered to control group, as well. Adverse effects of the antibiotic regimen were recorded for all patients. Six weeks after the cessation of probiotic intake, all patients underwent H. Pylori with fecal antigen of test, followed by a recurrence evaluation six months later. There was no significant difference in demographic data and presenting symptoms between the study groups. The eradication rate of H. pylori infection was significantly higher in probiotic group (78.4%), compared to that of placebo group (64.8%) (P=0.033). In addition, adverse events were significantly less prevalent in patients that received probiotic (P=0.047). Nonetheless, there was no significant difference in terms of infection recurrence during a 6-month follow-up (P=0.07). Double strain probiotic in combination with STT increased the eradication rate of H. pylori infection, while the adverse events due to antibiotic therapy decreased.

    AIM: To compare ecabet sodium and cimetidine in relieving symptoms of functional dyspepsia.METHODS: We performed a multi-center, prospective,randomized, double-blinded controlled trial to compare the clinical efficacy of ecabet sodium and cimetidine in patients with functional dyspepsia. Two-hundred and seventy-two patients with dyspeptic symptoms fulfilling the Rome-Ⅱ criteria were enrolled from 7 centers. In the study group (115 patients), 1.5 g ecabet sodium was given twice a day. In the control group (121 patients),400 mg cimetidine was given twice a day. Symptoms and parameters of quality of life were analyzed at baseline, 3,14, and 28 d after initiating the treatment.RESULTS: Two-hundred and thirty-six patients completed the clinical trial. After 4 wk of treatment,the rates of improvement in patients with dyspeptic symptoms were not different between two groups (77.4% in the ecabet group and 79.3% in the cimetidine group, respectively, P > 0.05). Likewise, the rates of symptomatic improvement were not different at 3 d and 14 d. The parameters of quality of life did not change significantly during the study period in both groups.There was no clinically significant adverse event in both groups.CONCLUSION: In patients with functional dyspepsia,ecabet sodium has similar clinical efficacy with cimetidine.

    To compare the efficacy of two commercially available, alcohol-based antiseptic solutions for preparation and care of central venous catheter (CVC) insertion sites, with and without octenidine dihydrochloride, a double-blind, randomized, controlled trial was undertaken in the haematology units and in one surgical unit of two university hospitals. Adult patients with a non-tunnelled CVC were randomly assigned to two different skin disinfection regimens at the insertion site: 0.1% octenidine with 30% 1-propanol and 45% 2-propanol, and as control 74% ethanol with 10% 2-propanol. Endpoints were (i) skin colonization at the insertion site; (ii) positive culture from the catheter tip (> or = 15 CFU); and (iii) occurrence of CVC-associated bloodstream infection (defined according to criteria set by the CDC). Four hundred patients with inserted CVC were enrolled from May 2002 through April 2005. Both groups were similar in respect of patient characteristics and co-morbidities. Skin colonization at the CVC insertion site during the first 10 days was significantly reduced by octenidine treatment (relative difference octenidine vs. control: 0.21; 95%CI: 0.11-0.39, p octenidine group (7.9%) than in the control group (17.8%): OR = 0.39 (95%CI: 0.20-0.80, p 0.009). Patients treated with octenidine had a non-significant reduction in catheter-associated bloodstream infections (4.1% vs. 8.3%; OR = 0.44; 95%CI: 0.18-1.08, p 0.081). Side effects were similar in both groups. This randomized controlled trial supports the results of two observational studies demonstrating octenidine in alcoholic solution to be a better option than alcohol alone for the prevention of CVC-associated infections.

    The optimal method of pain control after percutaneous nephrolithotomy (PCNL) remains controversial. We sought to determine whether intercostal nerve block with bupivicaine provided superior pain control, when compared with placebo, with a lower need for narcotics and improved health-related quality of life (HRQL) in the immediate postoperative period. Sixty-three patients were randomized to receive intercostal blockade with either 20 mL of 0.5% bupivacaine with epinephrine or 20 mL physiologic saline. All patients received intravenous narcotic patient-controlled analgesia (PCA) postoperatively. Data were collected on stone parameters, demographics, analgesic usage, length of stay, and HRQL as assessed by the Postoperative Recovery Scale. The mean age was 47.7±1.2 years; mean body mass index was 28.0±5.0 kg/m(2); mean stone diameter was 29.2±15.8 mm. Within the first 3 to 6 hours after surgery, there was a significant reduction in narcotic use for the group receiving intercostal nerve blockade with bupivacaine compared with placebo. At 3 hours, narcotic use was 2.4±3.1 mg vs 4.3±3.8 mg morphine equivalents (P=0.034), and within 6 hours of surgery, narcotic use was 5.9±6.1 mg vs 8.8±7.4 mg (P=0.096). Durable improvement in HRQL was also observed in patients receiving intercostal nerve blockade with bupivacaine compared with placebo (P=0.034). No complications were attributable to the intercostal nerve blocks in either group. Intercostal blockade with bupivacaine significantly improves both pain control and HRQL in the early postoperative period. The effectiveness of bupivacaine disappears within 6 hours of surgery, after which narcotic use becomes indistinguishable. Intercostal nerve blockade is an easy, safe, and inexpensive method that can be used to optimize pain control after PCNL.

    Objective:To evaluate the efficacy of tranexamic acid in reduction of blood loss during and after cesarean section.Methods:Women included in the current double blinded, randomized, controlled trial were recruited from women attending for elective cesarean section and randomized into two groups; study group: received tranexamic acid with induction of anesthesia plus10IU of oxytocin injection after delivery of the baby.Control group: received only oxytocin 10IU injection after delivery of the baby.Results:Twenty four hours post-operative hemoglobin level was significantly higher in study group(11.2±1.5 mg/dL) compared to control(9.6±1.2 mg/dL), also24 hours post-operative hematocrit was significantly higher in study group(30.2±6.6) compared to control(29.2±2.8).Calculated total blood loss from placental delivery till end of cesarean section was significantly less in study group compared to control(369.5±198.0 versus606.8±193.0 mL; respectively), also, calculated vaginal bleeding during first6 hours post-operative was significantly less in study group compared to control(85.0±30.7 mL versus130.8±49.3 mL, respectively).The incidence of post-partum hemorrhage was significantly less in study group compared to control(31.1% versus63.2%; respectively), also the need for iron replacement therapy was significantly less frequent in study group compared to control(0.9% versus6.6%, respectively). Conclusions:Tranexamic acid can be used safely to reduce blood loss during cesarean section. Reduced blood loss after tranexamic acid was associated with improvement of post-operative hemoglobin, hematocrit and with reduction of post-partum need for iron replacement.

    BACKGROUND Latrepirdine is an orally administered experimental small molecule that was initially developed as an antihistamine and subsequently was shown to stabilize mitochondrial membranes and function, which might be impaired in Huntington disease. OBJECTIVE To determine the effect of latrepirdine on cognition and global function in patients with mild to moderate Huntington disease. DESIGN Randomized, double-blind, placebo-controlled study. SETTING Sixty-four research centers in Australia, Europe, and North America. PATIENTS Four hundred three patients with mild to moderate Huntington disease and baseline cognitive impairment (Mini-Mental State Examination score, 10-26). INTERVENTION Latrepirdine (20 mg) vs matching placebo administered orally 3 times daily for 26 weeks. MAIN OUTCOME MEASURES The co-primary outcome measures were cognition as measured by the change in Mini-Mental State Examination score from baseline to week 26 and global function at week 26 as measured by the Clinician Interview-Based Impression of Change, plus carer interview, which ranges from 1 (marked improvement) to 7 (marked worsening). Secondary efficacy outcome measures included behavior, daily function, motor function, and safety. RESULTS The mean change in Mini-Mental State Examination score among participants randomized to latrepirdine (1.5-point improvement) did not differ significantly from that among participants randomized to placebo (1.3-point improvement) (P=.39). Similarly, the distribution of the Clinician Interview-Based Impression of Change, plus carer interview did not differ significantly among those randomized to latrepirdine compared with placebo (P=.84). No significant treatment effects were detected on the secondary efficacy outcome measures. The incidence of adverse events was similar between those randomized to latrepirdine (68.5%) and placebo (68.0%). CONCLUSION In patients with mild to moderate Huntington disease and cognitive impairment, treatment with

    Full Text Available Background: Oral aphthous is one of the most common oral mucosal inflammatory disorders which are very painful. There is no definite medical strategy up to now for aphthous treatment. Recently, some researchers have focused on immunomodulatory drugs such as tacrolimus and pimecrolimus in preventing aphthus recurrences. The aim of this study is to assess the effect of pimecrolimus cream against placebo in management of oral minor aphthous.Methods: The study is a randomized clinical trial, was done in “Shariati” hospital and Isfahan Skin Research Center. 62 patients with minor aphthuos were included and divided randomly to two groups (31 in each. In experimental group, pimecrolimus cream was applied for two weeks and cold cream for the same duration in control group. Patients were followed for 3 and one week; results were assessed in recovery after drug administration. Compared variables between two groups were including: the size of lesions, the time to recovery and pain intensity.Results: Results showed that mean size lesion in experimental and placebo group after complete recovery reduced (23.6 ±15.3 and 24.8 ±15 mm respectively but it was not significant (P: 0.1. Mean time for recovery in both groups was 8±2.2 and 9.5±2.5 respectively which was significant in pimecrolimus treated patients (P: 0.014. Also mean degree for pain intensity measured by pain scale method was reduced significantly in test group (6 ± 1.2 before treatment and 5.3 ± 1.1 after treatment, P<0.001.Conclusion: This study stated that pimecrolimus cream has an appropriate effect in reduction of recovery time and pain in minor aphthous compared to placebo but more clinical studies are needed to better conclusion.

    Full Text Available BACKGROUND: Pioglitazone, an oral anti-diabetic that stimulates the PPAR-gamma transcription factor, increased survival of mice with amyotrophic lateral sclerosis (ALS. METHODS/PRINCIPAL FINDINGS: We performed a phase II, double blind, multicentre, placebo controlled trial of pioglitazone in ALS patients under riluzole. 219 patients were randomly assigned to receive 45 mg/day of pioglitazone or placebo (one: one allocation ratio. The primary endpoint was survival. Secondary endpoints included incidence of non-invasive ventilation and tracheotomy, and slopes of ALS-FRS, slow vital capacity, and quality of life as assessed using EUROQoL EQ-5D. The study was conducted under a two-stage group sequential test, allowing to stop for futility or superiority after interim analysis. Shortly after interim analysis, 30 patients under pioglitazone and 24 patients under placebo had died. The trial was stopped for futility; the hazard ratio for primary endpoint was 1.21 (95% CI: 0.71-2.07, p = 0.48. Secondary endpoints were not modified by pioglitazone treatment. Pioglitazone was well tolerated. CONCLUSION/SIGNIFICANCE: Pioglitazone has no beneficial effects on the survival of ALS patients as add-on therapy to riluzole.

    The blood-red sap of Dragon's blood has been used in folk medicine for fractures, wounds, inflammation, gastrointestinal disorders, rheumatism, blood circulation dysfunctions, and cancer. Existing in vitro and in vivo bioactivity of this herb on different mechanisms of healing shows strong potential of this sap in wound healing. This clinical trial study was designated to evaluate the wound healing effect of Dragon's blood on human wounds. Sixty patients, between the ages of 14-65 years, who were referred to remove their skin tag, were assigned to this double-blind, placebo-controlled, randomized clinical trial and received either Dragon's blood or a placebo cream. They were visited on the 3rd, 5th, 7th, 10th, 14th, and 20th day of the trial to check the process of healing and to measure the wound's surface. At the end of trial, there was a significant difference in the mean duration of wound healing between the two groups (p = 0.0001). The phenolic compounds and the alkaloid taspine, which exist in Dragon's-blood resin, are probably the main reasons for the wound healing property of this plant. Being natural accessible, safe, and affordable makes Dragon's blood cream, a good choice for addition to the wound healing armamentarium. Further studies on wounds with different causes and among larger populations are suggested to ensure the effectiveness and safety of Dragon's blood.

    The effect of aspirin desensitization (AD) on immunologic profile of patients with AERD has been poorly understood. This study is aimed at investigating the effect of AD on clinical and immunological markers of patients with AERD. This randomized double-blind placebo-controlled trial comprised 34 adult patients (67.6% female) with chronic rhinosinusitis, nasal polyps, and aspirin-intolerant asthma. The active group underwent AD over a 2-day period with increasing doses of aspirin (60, 125, 325, and 625 mg), followed by receiving aspirin 625 mg twice daily for 6 months. Symptom scores and medication needs of patients with AERD who have undergone AD were significantly lower compared to the placebo group after 6 months (7.5 ± 3.5 vs. 10.6 ± 3.8 and 9.3 ± 2.0 vs. 11.0 ± 3.1, respectively, all p < 0.05). However, no significant difference was observed in serum concentration of IL-10, IFN-γ, and TGF-β between two groups neither at baseline nor at the end of study.

    Acute, non-clinical insomnia is not uncommon. Sufferers commonly turn to short-term use of herbal supplements to alleviate the symptoms. This placebo-controlled, double-blind study investigated the efficacy of LZComplex3 (lactium™, Zizyphus, Humulus lupulus, magnesium and vitamin B6), in otherwise healthy adults with mild insomnia. After a 7-day single-blind placebo run-in, eligible volunteers (n = 171) were randomized (1:1) to receive daily treatment for 2 weeks with LZComplex3 or placebo. Results revealed that sleep quality measured by change in Pittsburgh Sleep Quality Index (PSQI) score improved in both the LZComplex3 and placebo groups. There were no significant between group differences between baseline and endpoint on the primary outcome. The majority of secondary outcomes, which included daytime functioning and physical fatigue, mood and anxiety, cognitive performance, and stress reactivity, showed similar improvements in the LZComplex3 and placebo groups. A similar proportion of participants reported adverse events (AEs) in both groups, with two of four treatment-related AEs in the LZComplex3 group resulting in permanent discontinuation. It currently cannot be concluded that administration of LZComplex3 for 2 weeks improves sleep quality, however, a marked placebo response (despite placebo run-in) and/or short duration of treatment may have masked a potential beneficial effect on sleep quality.

    Full Text Available The blood-red sap of Dragon's blood has been used in folk medicine for fractures, wounds, inflammation, gastrointestinal disorders, rheumatism, blood circulation dysfunctions, and cancer. Existing in vitro and in vivo bioactivity of this herb on different mechanisms of healing shows strong potential of this sap in wound healing. This clinical trial study was designated to evaluate the wound healing effect of Dragon's blood on human wounds. Sixty patients, between the ages of 14–65 years, who were referred to remove their skin tag, were assigned to this double-blind, placebo-controlled, randomized clinical trial and received either Dragon's blood or a placebo cream. They were visited on the 3rd, 5th, 7th, 10th, 14th, and 20th day of the trial to check the process of healing and to measure the wound's surface. At the end of trial, there was a significant difference in the mean duration of wound healing between the two groups (p = 0.0001. The phenolic compounds and the alkaloid taspine, which exist in Dragon's-blood resin, are probably the main reasons for the wound healing property of this plant. Being natural accessible, safe, and affordable makes Dragon's blood cream, a good choice for addition to the wound healing armamentarium. Further studies on wounds with different causes and among larger populations are suggested to ensure the effectiveness and safety of Dragon's blood.

    Allograft tympano-ossicular systems (ATOS) have proven their use over many decades in tympanoplasty and reconstruction after resection of cholesteatoma. The transcranial bone plug technique has been used in the past 50 years to procure en bloc ATOS (tympanic membrane with malleus, incus and stapes attached). Recently, our group reported the feasibility of the endoscopic procurement technique. The aim of this study was to assess whether clinical outcome is equivalent in ATOS acquired by using the endoscopic procurement technique compared to ATOS acquired by using the transcranial technique. A double-blind randomized controlled audit was performed in a tertiary referral center in patients that underwent allograft tympanoplasty because of chronic otitis media with and without cholesteatoma. Allograft epithelialisation was evaluated at the short-term postoperative visit by microscopic examination. Failures were reported if reperforation was observed. Fifty patients underwent allograft tympanoplasty: 34 received endoscopically procured ATOS and 16 received transcranially procured ATOS. One failed case was observed, in the endoscopic procurement group. We did not observe a statistically significant difference between the two groups in failure rate. This study demonstrates equivalence of the clinical outcome of allograft tympanoplasty using either endoscopic or transcranial procured ATOS and therefore indicates that the endoscopic technique can be considered the new standard procurement technique. Especially because the endoscopic procurement technique has several advantages compared to the former transcranial procurement technique: it avoids risk of prion transmission and it is faster while lacking any noticeable incision.

A randomized, double-blind, controlled clinical trial was carried out over 12 weeks to compare the effects of P. ginseng (100 mg/d with amitriptyline (25 mg/d and placebo in 38 patients with fibromyalgia: 13 in Group I (amitriptyline, 13 in Group II (placebo, and 12 in Group III (P. ginseng. Ratings on the Visual Analogue Scale (VAS revealed a reduction in pain in the P. ginseng group (p < .0001, an improvement in fatigue (p < .0001 and an improvement in sleep (p < .001, with respect to baseline characteristics, but there were no differences between the three groups. With respect to anxiety, improvements occurred in the P. ginseng group compared to baseline (p < .0001; however, amitriptyline treatment resulted in significantly greater improvements (p < .05. P. ginseng reduced the number of tender points and improved patients' quality of life (using the Fibromyalgia Impact Questionnaire - FIQ; however, there were no differences between groups. The beneficial effects experienced by patients for all parameters suggest a need for further studies to be performed on the tolerability and efficacy of this phytotherapic as a complementary therapy for fibromyalgia.

    The efficacy and safety of oral Tolperisone HCL was evaluated in double blind, placebo-controlled, randomized trial in 72 patients with neurolathyrism in stages I, II, and III of the disease at Kolla Duba Health Centre of Dembia District of North Gondar between January and April 1995. Taken orally daily for 12 weeks, tolperisone HCL (Mydocalm) in a dose of 150 milligrams (mgs) twice daily significantly improved subjective complaints such as muscle cramps, heaviness of the legs, startle attacks, flexor spasms and repeated falls. An overall subjective improvement was observed in 75% of the patients on tolperisone HCL and 39% of the placebo group (P = 0.002). When objectively assessed spastic muscle tone in the abductors, stiffness of Achilles and spontaneous ankle clonus were significantly reduced in tolperisone HCL group (P values = 0.001, 0.04, and 0.0001, respectively). Walking ability and speed of walking was also significantly improved. The drug is most effective in relieving symptoms of stage I and stage II disease. Some adverse effects like muscle pain, generalized body weakness and dizziness were recorded in patients taking the drug but all were minor and self limited, none requiring discontinuation of treatment. It is concluded that tolperisone is a well tolerated and efficacious drug for symptomatic treatment of neurolathyrism.

    Abstract Background: Recalcitrant facial flat warts are caused by human papillomavirus and may persist for years despite treatment. Isotretinoin has demonstrated benefits in the treatment of recalcitrant, genital and common warts, but placebo-controlled trials have not been performed. To determine whether isotretinoin is safe and effective for recalcitrant facial flat warts. Isotretinoin 30 mg/day or placebo was administered to 16 and 15 patients, respectively, in double-blind, randomized fashion for 12 weeks. Cutaneous lesions were assessed and adverse events including serologic and ophthalmologic changes were recorded. It is considered that warts were recalcitrant if the patient was treated for at least 3 years with at least three of the following options: retinoids, 5-fluorouracil, imiquimod and cryotherapy using liquid nitrogen. Each patient in the istotretinoin group showed complete clearance of all flat warts, while none of the patients in the placebo group showed any improvement (p=0.0001). The most frequent adverse event was cheilitis. There were no statistically significant changes in the laboratory findings. The study design does not permit complete blinding of the dermatologist who can easily recognize the adverse effects of isotretinoin. The clinical findings, however, were so dramatic that this would not have impacted the findings. Another limitation of the study is a lack of follow-up to assess for recurrence after the drug was discontinued. Isotretinoin is an effective treatment for recalcitrant flat facial warts with a well-known, manageable safety profile.

    The effect of a mangosteen product containing multivitamins and essential minerals was tested on immune function and well-being in healthy adults. A randomized, double blinded, placebo-controlled study was conducted in 59 healthy human subjects (40-60 years old). Changes from baseline immune function were measured after a 30-day consumption of the mangosteen product and the placebo. The subjects' self-appraisal of their health status was also surveyed. A xanthone-rich mangosteen product intake increased mean values for peripheral T-helper cell frequency (P = .020) and reduced the serum C-reactive protein concentration (P = .014). Increases in peripheral CD4/CD8 double-positive (DP) T-cell frequency and serum complement C3, C4, and interleukin (IL)-1alpha concentrations were significantly higher in the experimental group than in the placebo group (DP, P = .038; C3, P = .017; C4, P = .031; IL-1alpha, P = .006). At the end of study, serum IL-1alpha and IL-1beta concentrations in the study group were significantly higher than that in the placebo group (IL-1alpha, P = .033; IL-1beta, P = .04). Furthermore, more participants in the experimental group reported greatly improved overall health status compared with participants receiving placebo (P = .001). The results indicated that the intake of an antioxidant-rich product significantly enhanced immune responses and improved the subject's self-appraisal on his or her overall health status.

    Antidepressant medication is often associated with sexual side effects. A double-blind, placebo-controlled study in men with lifelong rapid ejaculation was performed to assess the effects of two selective serotonin (5-HT) reuptake inhibitors--paroxetine and sertraline--and the 5-HT2 antagonist and 5-HT/noradrenaline reuptake inhibitor nefazodone on the latency to ejaculate. Forty-eight men with an intravaginal ejaculation latency time (IELT) of a maximum of 1 minute were randomly assigned to receive paroxetine (20 mg/day), sertraline (50 mg/day), nefazodone (400 mg/day), or placebo for 6 weeks. During the 1-month baseline and 6-week treatment period, IELTs were measured at home with a stopwatch. The trial was completed by 40 men. During the 6-week treatment period, the geometric mean IELT in the placebo group was stable at approximately 20 seconds. Analysis of variance revealed a between-group difference in the evolution of IELT delay over time (p = 0.002); the IELT after paroxetine and sertraline gradually increased to approximately 146 and 58 seconds, respectively, compared with 28 seconds in the nefazodone group. The paroxetine and sertraline groups differed significantly (p < 0.001 and p = 0.024, respectively) from placebo, but the nefazodone group did not (p = 0.85). Compared with baseline, paroxetine exerted the strongest delay in ejaculation, whereas sertraline delayed it only moderately. There was no clinically relevant delay in ejaculation with nefazodone.

    Intranasal (IN) midazolam is a commonly prescribed medication for pediatric sedation and anxiolysis. One of its most frequently encountered adverse effects is discomfort with administration. While it has been proposed that premedicating with lidocaine reduces this undesirable consequence, this combination has not been thoroughly researched. The objective of our study was to assess whether topical lidocaine lessens the discomfort associated with IN midazolam administration. This was a double-blind, randomized, placebo-controlled trial performed in an urban, academic pediatric emergency department. Children 6-12 years of age who were receiving IN midazolam for procedural sedation received either 4% lidocaine or 0.9% saline (placebo) via mucosal atomizer. Subjects were subsequently given IN midazolam in a similar fashion and then rated their discomfort using the Wong-Baker FACES Pain Rating Scale (WBS). The primary endpoint of WBS score was analyzed with a two-tailed Mann-Whitney U-test, with p midazolam administration (median WBS = 3, interquartile range [IQR] = 0-6) than those who received placebo (median WBS = 8, IQR = 2-9; p = 0.006). Premedication with topical lidocaine reduces the discomfort associated with administration of IN midazolam (ClinicalTrials.gov, NCT02396537). © 2016 by the Society for Academic Emergency Medicine.

The aim of this study was to investigate the effectiveness of probiotics in childhood constipation. Materials and Methods. In this placebo controlled trial, fifty-six children aged 4–12 years with constipation received randomly lactulose plus Protexin or lactulose plus placebo daily for four weeks. Stool frequency and consistency, abdominal pain, fecal incontinence, and weight gain were studied at the beginning, after the first week, and at the end of the 4th week in both groups. Results. Forty-eight patients completed the study. At the end of the fourth week, the frequency and consistency of defecation improved significantly (P=0.042 and P=0.049, resp.. At the end of the first week, fecal incontinence and abdominal pain improved significantly in intervention group (P=0.030 and P=0.017, resp. but, at the end of the fourth week, this difference was not significant (P=0.125 and P=0.161, resp.. A significant weight gain was observed at the end of the 1st week in the treatment group. Conclusion. This study showed that probiotics had a positive role in increasing the frequency and improving the consistency at the end of 4th week.

    Full Text Available : OBJECTIVE: Controlled hypotension is commonly used to achieve a bloodless operative field which is needed for successful FESS. This study was carried out to assess the hypotensive effect of dexmedetomidine (DEX during FESS. METHODS: Fifty ASA grades I and II patients of either sex aged 20–50 years undergoing FESS were randomly divided into two groups of 25 each. Group D received 10–15 min prior to induction of anesthesia 1 μg/kg IV bolus DEX diluted in 10 ml of normal saline over 10 min. Immediately thereafter an infusion of 0.4 μg/kg/hr of DEX commenced. Group C received placebo bolus and infusion of saline at a rate similar to DEX in Group D. Standard anesthetic technique was used. The surgical field was assessed using Average Category Scale and average blood loss was calculated. Hemodynamic variables (MAP and HR; emergence time and total recovery from anesthesia (Aldrete score ≥9 were recorded. RESULT: Group D reached the desired MAP (55-65 mmHg. In group D patients the average MAP was 55.9±5.3 mm of Hg, where as in group C it was 86.2±11.4 mm of Hg. Patients in group D had a better surgical field, and the duration of surgery was significantly reduced(78.34±16.7mins in group D vs 103.2±113.1 mins in group C The mean awakening time was significantly reduced in patients of Group D (9.1±2.7 mins in group D vs12.8±2.2 mins in group C when compared to patients of Group C. CONCLUSION: This study demonstrated that dexmedetomidine is a safe agent for controlled hypotension and is effective in providing ideal surgical field during FESS.

    Full Text Available BACKGROUND: Remote ischemic preconditioning (RIPC has been shown to enhance the tolerance of remote organs to cope with a subsequent ischemic event. We hypothesized that RIPC reduces postoperative neurocognitive dysfunction (POCD in patients undergoing complex cardiac surgery. METHODS: We conducted a prospective, randomized, double-blind, controlled trial including 180 adult patients undergoing elective cardiac surgery with cardiopulmonary bypass. Patients were randomized either to RIPC or to control group. Primary endpoint was postoperative neurocognitive dysfunction 5-7 days after surgery assessed by a comprehensive test battery. Cognitive change was assumed if the preoperative to postoperative difference in 2 or more tasks assessing different cognitive domains exceeded more than one SD (1 SD criterion or if the combined Z score was 1.96 or greater (Z score criterion. RESULTS: According to 1 SD criterion, 52% of control and 46% of RIPC patients had cognitive deterioration 5-7 days after surgery (p = 0.753. The summarized Z score showed a trend to more cognitive decline in the control group (2.16±5.30 compared to the RIPC group (1.14±4.02; p = 0.228. Three months after surgery, incidence and severity of neurocognitive dysfunction did not differ between control and RIPC. RIPC tended to decrease postoperative troponin T release at both 12 hours [0.60 (0.19-1.94 µg/L vs. 0.48 (0.07-1.84 µg/L] and 24 hours after surgery [0.36 (0.14-1.89 µg/L vs. 0.26 (0.07-0.90 µg/L]. CONCLUSIONS: We failed to demonstrate efficacy of a RIPC protocol with respect to incidence and severity of POCD and secondary outcome variables in patients undergoing a wide range of cardiac surgery. Therefore, definitive large-scale multicenter trials are needed. TRIAL REGISTRATION: ClinicalTrials.gov NCT00877305.

    There is uncertainty about the efficacy and tolerability of blonanserin in schizophrenia. PubMed, the Cochrane Library databases, PsycINFO, and Google Scholar were searched up to September 2012. A systematic review and meta-analysis of individual patient data from randomized, controlled trials comparing blonanserin with other antipsychotics were conducted. The risk ratio (RR), 95% confidence intervals (CI), numbers-needed-to-harm (NNH), and weighted mean difference (WMD) were calculated. Four studies (total n = 1080) were identified (vs. risperidone studies [n = 508], vs. haloperidol studies [n = 572]). Comparing blonanserin with other pooled antipsychotics, there were no significant differences in the Positive and Negative Syndrome Scale (PANSS) total score (p = 0.75), PANSS positive (p = 0.41), PANSS negative (p = 0.09), and PANSS general psychopathology subscale scores (p = 0.96), and response rate (p = 0.72). However, blonanserin showed greater efficacy in PANSS negative subscale scores compared with haloperidol (WMD = -1.29, CI = -2.29 to -0.30, p = 0.01, I(2) = 0%). No significant differences were found in discontinuation rates between blonanserin and other pooled antipsychotics (due to any cause: p = 0.29, inefficacy: p = 0.32, adverse events: p = 0.56). Blonanserin had a 0.31 lower risk of hyperprolactinemia than the other pooled antipsychotics (CI = 0.20-0.49, NNH = not significant). While dizziness (RR = 0.47, CI = 0.23-0.93, NNH = not significant) and akathisia (RR = 0.54, CI = 0.32-0.90, NNH = 7) occurred significantly less often with blonanserin than with haloperidol, blonanserin had a 1.62 higher risk of akathisia than risperidone (CI = 1.18-2.22, NNH = 8) [corrected]. Our results suggest that although blonanserin has a more beneficial effect on negative symptoms than haloperidol, there was a significant difference in the adverse events profile between blonanserin and other antipsychotics.

    Shivering, a common intraoperative problem under spinal anesthesia increases the oxygen consumption considerably and is uncomfortable and distressing to the patient, anesthesiologist as well as surgeon. The present study was designed to explore the effectiveness of tramadol, clonidine and dexmedetomidine in the treatment of post spinal anesthesia shivering and to look for their adverse effects. This prospective, randomized, double blinded control study was done on 90 patients who developed shivering under spinal anesthesia. They were randomly allocated into three groups with Group T receiving tramadol 1mg.kg(-1), Group C getting clonidine 1mcg.kg(-1) and Group D patients receiving dexmedetomidine 0.5mcg.kg(-1). The time taken to control shivering, recurrence rate, hemodynamic variables, sedation score and adverse effects were observed. Dexmedetomidine was faster in the control of shivering in 5.7±0.79minutes (min) whereas tramadol took 6.76±0.93min and clonidine was slower with 9.43±0.93min. The recurrence rate was much lower in the dexmedetomidine group with 3.3% than for clonidine (10%) and tramadol (23.3%) group. The sedation achieved with dexmedetomidine was better than clonidine and tramadol. The tramadol group had more cases of vomiting (four) and dexmedetomidine group had six cases of hypotension and two cases of bradycardia. Two of the clonidine patients encountered bradycardia and hypotension. Dexmedetomidine is better than tramadol and clonidine in the control of shivering because of its faster onset and less recurrence rate. Though complications are encountered in the dexmedetomidine group, they are treatable. Copyright © 2016 Sociedade Brasileira de Anestesiologia. Publicado por Elsevier Editora Ltda.

    Full Text Available Objective: This study investigated the efficacy of bupivacaine wound infusion for pain control and opioid sparing effect after cesarean delivery.Materials and methods: We conducted a randomized double blind, placebo controlled clinical trial on 60 parturients undergoing cesarean section at a university hospital in Tehran. Patients were randomized to receive a pump infusion system that was filled with either 0.25% bupivacaine or equal volume of distilled water. A catheter was placed above the fascia and connected to electronic pump for 24 hours. Postoperative analog pain scores and morphine consumption were assessed at 6, 12 and 24 hours. Also time interval to first ambulation, length of hospitalization, complications and patient satisfaction were recorded. Data were analyzed using the SPSS software and P < 0.05 was considered statistically significant. Mann-Whitney u-test, student t-test and chi-square were used. Results: There were no differences in patient demographics and length of hospitalization and patient-generated resting pain scores between the two groups. Pain scores after coughing and leg raise during the first 6 postoperative hours were significantly less in the Bupivacaine group (P<0.001. The total dose of morphine consumption during the 24 hours study period was 2.5 ± 2.5 mg vs. 7.3 ± 2.7 mg for the bupivacaine and control groups, respectively (P<0.001. Compared with the control group, time to first ambulation was shorter in the bupivacaine group (11± 5h vs. 16 ± 4h (P< 0.01. Conclusion: Bupivacaine wound infusion was a simple and safe technique that provides effective analgesia and reduces morphine requirements after cesarean delivery.

    Full Text Available Most patients with fibromyalgia use complementary and alternative medicine (CAM. Properly designed controlled trials are necessary to assess the effectiveness of these practices. This study was a randomized, double-blind, placebo-controlled, early phase trial. Fifty patients seen at a fibromyalgia outpatient treatment program were randomly assigned to a daily soy or placebo (casein shake. Outcome measures were scores of the Fibromyalgia Impact Questionnaire (FIQ and the Center for Epidemiologic Studies Depression Scale (CES-D at baseline and after 6 weeks of intervention. Analysis was with standard statistics based on the null hypothesis, and separation test for early phase CAM comparative trials. Twenty-eight patients completed the study. Use of standard statistics with intent-to-treat analysis showed that total FIQ scores decreased by 14% in the soy group (P = .02 and by 18% in the placebo group (P < .001. The difference in change in scores between the groups was not significant (P = .16. With the same analysis, CES-D scores decreased in the soy group by 16% (P = .004 and in the placebo group by 15% (P = .05. The change in scores was similar in the groups (P = .83. Results of statistical analysis using the separation test and intent-to-treat analysis revealed no benefit of soy compared with placebo. Shakes that contain soy and shakes that contain casein, when combined with a multidisciplinary fibromyalgia treatment program, provide a decrease in fibromyalgia symptoms. Separation between the effects of soy and casein (control shakes did not favor the intervention. Therefore, large-sample studies using soy for patients with fibromyalgia are probably not indicated.

    Full Text Available Current standardized treatments for cognitive impairment in attention-deficit/hyperactivity disorder remain limited and their efficacy restricted. Transcranial direct current stimulation (tDCS is a promising tool for enhancing cognitive performance in several neuropsychiatric disorders. Nevertheless, the effects of tDCS in reducing cognitive impairment in patients with attention-deficit/hyperactivity disorder (ADHD have not yet been investigated.A parallel, randomized, double-blind, sham-controlled trial was conducted to examine the efficacy of tDCS on the modulation of inhibitory control in adults with ADHD. Thirty patients were randomly allocated to each group and performed a go/no-go task before and after a single session of either anodal stimulation (1 mA over the left dorsolateral prefrontal cortex or sham stimulation.A nonparametric two-sample Wilcoxon rank-sum (Mann-Whitney test revealed no significant differences between the two groups of individuals with ADHD (tDCS vs. sham in regard to behavioral performance in the go/no go tasks. Furthermore, the effect sizes of group differences after treatment for the primary outcome measures-correct responses, impulsivity and omission errors--were small. No adverse events resulting from stimulation were reported.According to these findings, there is no evidence in support of the use of anodal stimulation over the left dorsolateral prefrontal cortex as an approach for improving inhibitory control in ADHD patients. To the best of our knowledge, this is the first clinical study to assess the cognitive effects of tDCS in individuals with ADHD. Further research is needed to assess the clinical efficacy of tDCS in this population.ClinicalTrials.gov NCT01968512.

    Nonsteroidal anti-inflammatory drugs are a standard treatment option for muscle strain; however, side effects persist. This clinical trial was designed to compare the efficacy of Plai cream compared to placebos in adult patients with muscle strain. In this randomized, double-blind, placebo-controlled trial, 140 participants aged over 18 years with muscle strain were randomized to receive either Plai cream (n = 70 patients, treatment group) or placebos (n = 70 patients, control group) . Outcome assessments included the visual analog scale (VAS), quality of life (QoL), the amount of remaining cream, and the number of acetaminophen tablets used. After 2 weeks, the mean pain scores following treatment with both Plai cream and placebos in patients with muscle strain decreased from baseline to the end of the study at week 2. However, no significant difference for VA S score was found. The QoL of the two groups showed improvements in QoL as witnessed by increased mean QoL scores from baseline to week 2; however, these differences were not statistically significant. In general, mean QoL scores above 50 indicate good quality of life. The amount of Plai cream used reduced from baseline to week 2, but no significant difference in the amount of cream remaining was found between the two groups at each visit. Similarly, the number of acetaminophen tablets used was not statistically different between the treatment and control groups. There was no difference in pain reduction in the 2-week period between patients with muscle strain using Plai cream and those given placebos, but Plai cream tended to reduce pain in the long term. No side effects were found from Plai cream, so this non-invasive treatment may be offered to patients.

    Full Text Available Menopause is one of the most critical periods of woman's life. With reducing of ovarian estrogen; women are more prone to psychological and physical symptoms. The present study aimed to investigate the effect of melatonin on the climacteric symptoms.The present double blind, placebo randomized controlled clinical trial was conducted on 240 menopausal women (40 - 60 years old referring to the gynecology clinics of Shiraz University of Medical Sciences (January - November 2012. The participants were randomly divided into two groups through sortition. Demographic characteristics, Goldberg's general health questionnaire (GHQ, Greene Climacteric Scale and level of Follicle Stimulating Hormone (FSH were determined for both groups before the intervention. The intervention group received one 3mg melatonin tablet each night for 3 months and the control group received the placebo in the same period. Changes of climacteric symptoms and drug complications were measured 1, 2 and 3 months after the intervention.We analyzed the data of 99 postmenopausal women in the intervention group and 101 postmenopausal women in the control group. In the melatonin group, the climacteric symptoms score decreased from 35.73+11.6 to 17.09+10.22 during the 3-month study period and regardless of time, a significant difference was observed between the two groups (P<0.001. In addition, a significant difference was found between the two groups regarding various dimensions of the climacteric symptoms over time (P<0.001. No significant difference was found regarding side effects between the two groups (P= 0.135.The study findings showed that using melatonin improved the climacteric symptoms.

    Full Text Available Background: Patients with arrested preterm labor (PTL are at increased risk for recurrence ofpreterm birth (PTB. Maintenance tocolysis after arrest of acute PTL is of questionable value. Theobjective of this study was to evaluate the efficacy of 200 mg vaginal progesterone in order toprevent PTB in women with episodes of threatened PTL.Materials and Methods: This is a randomized double blind clinical trial study.Women with singletonpregnancies between 28-36 weeks of gestation, who were hospitalized for PTL were included. Atotal of 173 pregnant patients were randomly allocated to receive 200 mg vaginal progesteronesuppositories (n=86 or placebo (n=87 daily until the 36th gestational week. The two groups werecompared relative to demographic characteristics, incidence of PTB before 34 and 37 weeks, andmaternal and neonatal complications. Data were analyzed by chi-square and Fisher’s exact tests.Results: Mean latency until delivery in the cases was longer than the control group (23.88 ± 18.01vs. 16.67 ± 12.9; p=0.004.Treatment with progesterone was not associated with a reduction inthe rate of PTB before 34 weeks [cases: 9 (10.8% vs. controls: 8 (10%] and 37 weeks [cases: 45(54.2% vs. controls: 33 (41.2%]. Log rank analysis revealed a significant difference for mean timeto delivery between the two groups (p=0.028. There were no significant differences for neonataland maternal complications in the two groups.Conclusion: Prophylactic administration of 200 mg vaginal progesterone suppositories aftersuccessful tocolysis in patients with threatened idiopathic PTL is associated with a longer latencyto delivery, but failed to reduce the rate of PTB (Registeration Number: IRCT138706051096N1.

    Full Text Available Sutherlandia frutescens (L. R. Br. is widely used as an over the counter complementary medicine and in traditional medications by HIV seropositive adults living in South Africa; however the plant's safety has not been objectively studied. An adaptive two-stage randomized double-blind placebo controlled study was used to evaluate the safety of consuming dried S. frutescens by HIV seropositive adults with CD4 T-lymphocyte count of >350 cells/μL.In Stage 1 56 participants were randomized to S. frutescens 400, 800 or 1,200 mg twice daily or matching placebo for 24 weeks. In Stage 2 77 additional participants were randomized to either 1,200 mg S. frutescens or placebo. In the final analysis data from Stage 1 and Stage 2 were combined such that 107 participants were analysed (54 in the S. frutescens 1,200 mg arm and 53 in the placebo arm.S. frutescens did not change HIV viral load, and CD4 T-lymphocyte count was similar in the two arms at 24 weeks; however, mean and total burden of infection (BOI; defined as days of infection-related events in each participant was greater in the S. frutescens arm: mean (SD 5.0 (5.5 vs. 9.0 (12.7 days (p = 0.045, attributed to two tuberculosis cases in subjects taking isoniazid preventive therapy (IPT.A possible interaction between S. frutescens and IPT needs further evaluation, and may presage antagonistic interactions with other herbs having similar biochemical (antioxidant properties. No other safety issues relating to consumption of S. frutescens in this cohort were identified.ClinicalTrials.gov NCT00549523.

    Full Text Available Many patients experience pain and discomfort after colonoscopy. Carbon dioxide (CO2 can reduce periprocedural pain although air insufflation remained the standard procedure. The objective of this double-blinded, randomized controlled trial was to evaluate whether CO2 insufflation does decrease pain and bloating during and after colonoscopy compared to room air. Methods. 219 consecutive patients undergoing colonoscopy were randomized to either CO2 or air insufflation. Propofol was used in all patients for sedation. Transcutaneous CO2 was continuously measured with a capnograph as a safety parameter. Pain, bloating, and overall satisfaction were assessed at regular intervals before and after the procedure. Results(data are mean ±SD. 110 patients were randomized to CO2 and 109 to room air. The baseline characteristics were similar in both groups. The mean propofol dose was not different between the treatments, as were the time to reach the ileum and the withdrawal time. pCO2 at the end of the procedure was 35.2±4.3 mmHg (CO2 group versus 35.6±6.0 mmHg in the room air group (>.05. No relevant complication occurred in either group. There was significantly less bloating for the CO2 group during the postprocedural recovery period (<.001 and over the 24-hour period (<.001. Also, patients with CO2 insufflation experienced significantly less pain (=.014. Finally, a higher overall satisfaction (=.04 was found in the CO2 group. Conclusions. This trial provides compelling evidence that CO2 insufflation significantly reduces bloating and pain after routine colonoscopy in propofol-sedated patients. The procedure is safe with no significant differences in CO2 between the two groups.

    Niacinamide inhibits intestinal sodium/phosphorus transporters and reduces serum phosphorus in open-label studies. A prospective, randomized, double-blind, placebo-controlled crossover trial was performed for assessment of the safety and efficacy of niacinamide. Hemodialysis patients with phosphorus levels > or =5.0 mg/dl were randomly assigned to 8 wk of niacinamide or placebo, titrated from 500 to 1500 mg/d. After a 2-wk washout period, patients switched to 8 wk of the alternative therapy. Vitamin D analogs and calcimimetics were held constant; phosphorus binders were not changed unless safety criteria were met. Thirty-three patients successfully completed the trial. Serum phosphorus fell significantly from 6.26 to 5.47 mg/dl with niacinamide but not with placebo (5.85 to 5.98 mg/dl). A concurrent fall in calcium-phosphorus product was seen with niacinamide, whereas serum calcium, intact parathyroid hormone, uric acid, platelet, triglyceride, LDL, and total cholesterol levels remained stable in both arms. Serum HDL levels rose with niacinamide (50 to 61 mg/dl but not with placebo. Adverse effects were similar between both groups. Among patients who were > or =80% compliant, results were similar, although the decrease in serum phosphorus with niacinamide was more pronounced (6.45 to 5.28 mg/dl) and the increase in HDL approached significance (49 to 58 mg/dl). In hemodialysis patients, niacinamide effectively reduces serum phosphorus when co-administered with binders and results in a potentially advantageous increase in HDL cholesterol. Further study in larger randomized trials and other chronic kidney disease populations is indicated.

    This study evaluated the efficacy and tolerability of desvenlafaxine succinate (desvenlafaxine) in the treatment of major depressive disorder (MDD). In this 8-week, multicenter, randomized, double-blind, placebo-controlled trial, adult outpatients (aged 18-75 years) with a primary diagnosis of MDD (DSM-IV criteria) were randomly assigned to treatment with desvenlafaxine (100-200 mg/day) or placebo. The primary outcome measure was the 17-item Hamilton Rating Scale for Depression (HAM-D(17)) score at final on-therapy evaluation. The Clinical Global Impressions-Improvement scale (CGI-I) was the key secondary measure. Other secondary measures included the Montgomery-Asberg Depression Rating Scale (MADRS), Clinical Global Impressions-Severity of Illness scale, Visual Analog Scale-Pain Intensity (VAS-PI) overall and subcomponent scores, and HAM-D(17) response and remission rates. The study was conducted from June 2003 to May 2004. Of the 247 patients randomly assigned to treatment, 234 comprised the intent-to-treat population. Following titration, mean daily desvenlafaxine doses ranged from 179 to 195 mg/day. At endpoint, there were no significant differences in scores between the desvenlafaxine (N = 120) and placebo (N = 114) groups on the HAM-D(17) or CGI-I. However, the desvenlafaxine group had significantly greater improvement in MADRS scores (p = .047) and in VAS-PI overall pain (p = .008), back pain (p = .006), and arm, leg, or joint pain (p Desvenlafaxine was generally safe and well tolerated. In this study, it did not show significantly greater efficacy than placebo on the primary or key secondary efficacy endpoints, but it did demonstrate efficacy on an alternate depression scale and pain measure associated with MDD.

    A growing number of people is subject to age-related cognitive impairment due to the proportional increase of the ageing population. Therefore, there is a growing interest in cognition-enhancing substances. The efficacy of an alcohol/water extract of Ginkgo biloba in elderly individuals with memory- and/or concentration complaints was tested in a randomized, double-blind, placebo-controlled study by using both subjective and objective parameters. After a wash-out period of 4 weeks 241 non-institutionalised patients in the age range 55-86 years were randomly allocated to receive either Ginkgo biloba alcohol/water extract in a high dose (HD), a low dose (LD) or a placebo (PL) for 24 weeks. Patients were assessed using a psychometric testbattery in the following order: Expended Mental Control Test (EMCT) measuring attention and concentration, Benton Test of Visual Retention-Revised (measures short term visual memory), Rey Test part 1 (measures short term memory and learning curve), Beck Depressive Inventory (BDI) measuring the presence and severeness of a depression in order to exclude depressive patients and Rey Test part 2 (measures long term memory: recognition). Furthermore, subjective perception of memory and concentration was measured. 197 patients completed the study (mean MMSE score: 26.29). In the subjective test, the EMCT, the Rey 1 and Rey 2 no significant differences in improvement in time between the groups were observed. In the Benton test increases of 18%, 26% and 11% (expressed as percentage of baseline scores) were observed in the HD, LD and PL respectively (MANOVA; p = 0.0076). No substantial correlation was observed between subjective perception of the severeness of memory complaints and the objective test results. No differences in the number of (gastrointestinal) side effects were observed between placebo and verum groups. These results indicate that the use of Ginkgo extracts in elderly individuals with cognitive impairment might be promising

    Full Text Available Objectives. We aimed at evaluating both the efficacy and safety of TJ-54 (Yokukansan in patients with treatment-resistant schizophrenia. This randomized, multicenter, double-blind, placebo-controlled study was conducted. Methods. One hundred and twenty antipsychotic-treated inpatients were included. Patients were randomized to adjuvant treatment with TJ-54 or placebo. During a 4-week follow-up, psychopathology was assessed using the Positive and Negative Syndrome Scale (PANSS. Results. TJ-54 showed a tendency of being superior to placebo in reduction total, positive, and general PANSS scores in treatment-resistant schizophrenia, but the difference was not statistically significant in both per-protocol set (PPS and intention-to-treat (ITT. However, in PPS analysis, compared to the placebo group, the TJ-54 group showed statistically significant improvements in the individual PANSS subscale scores for lack of spontaneity and flow of conversation (TJ-54: −0.23±0.08; placebo: −0.03±0.08, P<0.018, tension (TJ-54: −0.42±0.09; placebo: −0.18±0.09, P<0.045, and poor impulse control (TJ-54: −0.39±0.10; placebo: −0.07±0.10, P<0.037. Conclusions. The results of the present study indicate that TJ-54 showed a tendency of being superior to placebo in reduction PANSS scores in treatment-resistant schizophrenia, but the difference was not statistically significant. However, compared to the placebo group, TJ-54 group showed statistically significant improvements in the individual PANSS subscale scores.

    Shoulder pain is the third most common musculoskeletal problem and accounts for 5% of general practitioner consultations. Although many treatments are described, there is no consensus on optimal treatment and up to 40% of patients still have pain 12 months after initially seeking help for pain. Previously, the effect of transcutaneous pulsed radiofrequency treatment (TCPRFT) was evaluated in a retrospective audit that showed good pain relief for a mean 395 days and justified this randomized sham controlled trial. In this study, 51 patients entered into a randomized double-blinded, placebo controlled study of TCPRFT. Patients were assessed at 4 and 12 weeks by a blinded observer and compared with baseline. We observed sustained reductions in pain at night, pain with activity, and functional improvement at 4 and 12 weeks with active but not sham TCPRFT. The 25 subjects who received active treatment showed statistically significant reductions of 24/100 in pain at night and 20/100 of pain with activity at 4 weeks and 18/100 and 19/100, respectively, at 12 weeks from baseline. Statistically significant lower Brief Pain Inventory pain and function scores (4 and 12 weeks), improved pain self-efficacy (4 weeks), Oxford Shoulder scores (12 weeks), and internal rotation (12 weeks) were seen. Pain at both rest and shoulder elevation were not improved by active treatment. No complications were seen. This study of a simple, low risk, outpatient treatment confirms the findings of our earlier study of TCPRFT for knee pain and shoulder pain audit that transcutaneous pulsed radiofrequency treatment may help some people with painful shoulders.

    Constipation is a frustrating symptom affecting 3% of children worldwide. A fermented dairy product containing Bifidobacterium lactis strain DN-173 010 was effective in increasing stool frequency in constipated women. Our aim was to assess the effects of this product in constipated children. In this prospective randomized, double-blind, controlled trial, 159 constipated children (defecation frequency DN-173 010 (n = 79) or a control product (n = 80) twice a day for 3 weeks. The primary endpoint was the change in stool frequency from baseline to after 3 weeks of product consumption. Analyses were by intention to treat. Eleven children did not return to any follow-up visit (5 in the probiotic group, 6 in the control group) and were therefore excluded from the final analysis. Thus, 74 children in each group were analyzed. The change in stool frequency from baseline to after 3 weeks of product consumption increased in both groups, but the difference was not statistically significant (2.9 ± 3.2 in probiotic group versus 2.6 ± 2.6 in control group, P = .35). There were no serious adverse events. In constipated children, the fermented dairy product containing B lactis strain DN-173 010 did increase stool frequency, but this increase was comparable in the control group. There is currently not sufficient evidence to recommend fermented dairy products containing B lactis strain DN-173 010 in this category of patients. Future studies should focus on whether a longer period of probiotic products is more effective in children who have a short history of constipation.

    Home visit program can be effective in infants' growth and development. The present study aimed to investigate the effect of home visit program on preterm infants' growth and development within 6 months. It was a double-blind clinical trial study. The study was conducted in Hafez, Hazrat-e-Zeinab, and Namazee Hospitals affiliated to Shiraz University of Medical Sciences, Shiraz, Iran from 2010 to 2011. Preterm infants were divided into intervention (n=30) and control groups (n=30) through blocked randomization. The intervention group received home visit training program for 6 months, while the control group only received the hospital's routine care. Then, the infants' growth indexes, including weight, height, and head circumference, and development criteria were compared on the first day of admission in Neonatal Intensive Care Unit, and then first, second, third, and sixth months. The data were analyzed using Chi-square, independent t-test, and repeated measures ANCOVA. The mean weight of the intervention and control group infants was 7207.3±1129.74 and 6366.7±922.26 gr in the sixth month. Besides, the intervention group infants' mean weight was higher compared to the control group after six months (t=-3.05, P=0.03). Also, a significant difference was found between the two groups regarding development indexes, such as following moving objects with the head, keeping the head stable when changing the position from lying to sitting,  producing "Agha" sound, and taking objects by hand (Pdevelopment indexes at the sixth month. Considering the importance of infants' growth and development, healthcare staff is recommended to incorporate home visit training into their programs, so that steps can be taken towards improvement of preterm infants' health.

    The preoperative or intraoperative administration of intravenous magnesium sulfate has been approved as an accepted medication for stabilizing hemodynamic indices during surgeries. Intraoperative blood loss during orthognathic surgery is frequently abundant and sometimes requires blood transfusion. The present trial addressed the efficacy of intravenous magnesium sulfate on deliberating hypotension and bleeding reduction in patients undergoing bimaxillary orthognathic surgery. This randomized double-blinded placebo controlled trial was conducted on 52 consecutive patients who underwent orthognathic surgery. The participants were randomly assigned to two groups receiving intravenous magnesium sulfate 30 mg/kg body weight bolus for 15 minutes immediately before anesthesia induction, followed by 10 mg/kg/hr dissolved in saline via pump infusion (n=26) and the second group received placebo as same bolus volume of normal saline in a 15-minute intravenous infusion which was continued until the end of operation (n=26). Both systolic and diastolic blood pressures were measured before anesthesia induction at baseline, during surgery, and at the end of the surgery. Intraoperative blood loss was also determined. Systolic and diastolic blood pressures did not differ between the two groups at baseline. Although a downward trend of both systolic and diastolic blood pressures was seen during the operation in both groups, the decrease in blood pressures occurred with greater gradient in the group administered magnesium sulfate. Assessing difference in the trend of the changes in systolic and diastolic blood pressures between the two study groups (adjusted for gender, age, mean body mass index, and time of surgery) showed different trends in the changes of blood pressures. No differences were observed in blood loss or blood product requirement between the two groups. The administration of intravenous magnesium sulfate can attenuate both systolic and diastolic blood pressures during

    Taurine, the most abundant, semiessential, sulfur-containing amino acid, is well known to lower blood pressure (BP) in hypertensive animal models. However, no rigorous clinical trial has validated whether this beneficial effect of taurine occurs in human hypertension or prehypertension, a key stage in the development of hypertension. In this randomized, double-blind, placebo-controlled study, we assessed the effects of taurine intervention on BP and vascular function in prehypertension. We randomly assigned 120 eligible prehypertensive individuals to receive either taurine supplementation (1.6 g per day) or a placebo for 12 weeks. Taurine supplementation significantly decreased the clinic and 24-hour ambulatory BPs, especially in those with high-normal BP. Mean clinic systolic BP reduction for taurine/placebo was 7.2/2.6 mm Hg, and diastolic BP was 4.7/1.3 mm Hg. Mean ambulatory systolic BP reduction for taurine/placebo was 3.8/0.3 mm Hg, and diastolic BP was 3.5/0.6 mm Hg. In addition, taurine supplementation significantly improved endothelium-dependent and endothelium-independent vasodilation and increased plasma H2S and taurine concentrations. Furthermore, changes in BP were negatively correlated with both the plasma H2S and taurine levels in taurine-treated prehypertensive individuals. To further elucidate the hypotensive mechanism, experimental studies were performed both in vivo and in vitro. The results showed that taurine treatment upregulated the expression of hydrogen sulfide-synthesizing enzymes and reduced agonist-induced vascular reactivity through the inhibition of transient receptor potential channel subtype 3-mediated calcium influx in human and mouse mesenteric arteries. In conclusion, the antihypertensive effect of chronic taurine supplementation shows promise in the treatment of prehypertension through improvement of vascular function. © 2016 American Heart Association, Inc.

    In Traditional Iranian Medicine (TIM), Melissa officinalis L. is commonly regarded as an effective therapy for heart palpitations. Heart palpitation is a common complaint that is often benign and associated with a marked distress that makes the condition difficult to treat. Herbal medicines provide an alternative to conventional drugs for treating various kinds of diseases. This study was done as a double blind randomized placebo-controlled clinical trial to evaluate the efficacy and safety of the dried extract of M. officinalis on adults suffering from benign palpitations. Eligible volunteers were randomly assigned as outpatients to a 14 day treatment with 500 mg twice a day of lyophilized aqueous extract of M. officinalis leaves (or placebo). Participants in the tests, physicians and researchers were blind to group assignments. Both primary and secondary outcomes were patient-reported. Primary outcomes were obtained from two measures: mean frequency of palpitation episodes per week, derived from patients׳ diaries, and mean intensity of palpitation estimated through Visual Analogue Scale (VAS) in a self-report questionnaire. Psychiatric symptoms (somatization, anxiety and insomnia, social dysfunction and severe depression) were evaluated as secondary outcomes by General Health Questionnaire-28 (GHQ-28), before and after intervention. Fifty-five volunteers out of 71 recruited study subjects completed the trial. Results showed that 14-day of treatment with lyophilized aqueous extract of M. officinalis leaves reduced frequency of palpitation episodes and significantly reduced the number of anxious patients in comparison to the placebo (P=0.0001, P=0.004 resp.). Also, M. officinalis extract showed no indication of any serious side effects. Lyophilized aqueous extract of M. officinalis leaves may be a proper and safe herbal drug for the treatment of benign palpitations. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available BACKGROUND AND AIMS: Obesity and its associated cardiometabolic co-morbidities are increasing worldwide. Since thyroid hormone mimetics are capable of uncoupling the beneficial metabolic effects of thyroid hormones from their deleterious effects on heart, bone and muscle, this class of drug is considered as adjacent therapeutics to weight-lowering strategies. This study investigated the safety and efficacy of TRC150094, a thyroid hormone mimetic. MATERIALS AND METHODS: This 4-week, randomized, placebo-controlled, double-blind trial was conducted in India and The Netherlands. Forty subjects were randomized at a 1:1 ratio to receive either TRC150094 dosed at 50 mg or placebo once daily for 4 weeks. Hyperinsulinemic euglycemic clamp and (1H-Magnetic Resonance Spectroscopy (MRS were performed before and after treatment. RESULTS: At baseline, subjects were characterized by markedly impaired hepatic and peripheral insulin sensitivity. TRC150094 dosed 50 mg once daily was safe and well tolerated. Hepatic nor peripheral insulin sensitivity improved after TRC150094 treatment, expressed as the suppression of Endogenous Glucose Production from 59.5 to 62.1%; p = 0.477, and the rate of glucose disappearance from 28.8 to 26.4 µmol kg(-1min(-1, p = 0.185. TRC150094 administration did not result in differences in fasting plasma free fatty acids from 0.51 to 0.51 mmol/L, p = 0.887 or in insulin-mediated suppression of lipolysis from 57 to 54%, p = 0.102. Also, intrahepatic triglyceride content was unaltered. CONCLUSION: Collectively, these data show that, in contrast to the potent metabolic effects in experimental models, TRC150094 at a dose of 50 mg daily does not improve the metabolic homeostasis in subjects at an increased cardiometabolic risk. Further studies are needed to evaluate whether TRC150094 has beneficial effects in patients with more severe metabolic derangement, such as overt diabetes mellitus and hypertriglyceridemia.

    A total of 478 patients with endoscopically confirmed duodenal ulcer entered this randomized, parallel, double-blind trial. Patients were randomly assigned to receive ebrotidine (N-[(E)-[[2-[[[2-[(diaminomethylene)amino]- 4-thiazolyl]methyl]thio]ethyl]amino]methylene]-4-bromo-benzenesulfona mid e, CAS 100981-43-9, FI-3542) 400 mg or ranitidine 300 mg tablets (4:1) respectively, administered in single evening doses. Endoscopy, clinical examination and symptom assessment were performed at baseline and at weeks 4 and 8. Safety evaluations including laboratory tests, treatment compliance and antacid consumption checks were conducted at the beginning and/or at the 4 and 8 week visits. Patients whose ulcer showed endoscopic healing at the 4-week control left the study. Both groups were matched in all parameters studied. The healing rates at 4 weeks were 76.4% and 75.3% for ebrotidine and ranitidine respectively, while at 8 weeks the final rates were 95% and 91.8% respectively. Accompanying symptoms disappeared rapidly and the patients returned to normal. Smoking proved to be a highly significant negative risk factor, since healing rates were 83.4% and 71.2% at 4 weeks and 97.4% and 92.3% at 8 weeks in non-smokers and smokers respectively (p = 0.0046). Smokers treated with ranitidine showed significantly lower final healing rates than non-smokers (86% vs 100%; p = 0.0358), while the healing rates among patients treated with ebrotidine were similar regardless of whether they were smokers or not (93.9% and 96.7% N.S.). Ebrotidine (94%) proved to be more effective than ranitidine (86%) in smokers with higher healing rates (p < 0.05). Alcohol intake showed no significant relationship with the healing rates. Both drugs demonstrated an excellent safety. There were no changes in blood parameters, and no significant adverse events were reported.

    Full Text Available Introduction: Over the years chlorhexidine (CHX, triclosan and sodium fluoride (NaF mouth rinses are used alone or combined in the prevention of dental diseases. However, at present little is known about the combined effects of NaF + triclosan and CHX + NaF + triclosan mouth rinses on reducing dental plaque and gingivitis. Aim: The aim was to determine the efficacy of mouth rinses used as adjuncts to regular oral hygiene measures on reducing dental plaque and gingivitis. Materials and Methods: A randomized, placebo-controlled, double-blind, parallel-group study was conducted for 6-month, among 12-15 years old school children in Nellore, India. Eligible subjects (n = 210 with consent were randomly allocated to four groups and were provided with a mouth rinse (Group A = 0.2% CHX; Group B = 0.05% sodium fluoride + 0.03% triclosan; Group C = 0.2% CHX + 0.05% sodium fluoride + 0.03% triclosan; Group D = Placebo. All subjects used 10 ml of mouth rinse, once daily for 60 s. The clinical parameters evaluated were plaque index (PlI and gingival Index (GI. Statistical significance within and between four groups was tested using one-way analysis of variance (ANOVA, repeated measures ANOVA with post-hoc and paired t-test. Results: At the end of clinical trial, the three test groups showed statistically significant (P < 0.001 reduction in PlI and GI scores compared with placebo group. Conclusion: The active agents demonstrated highly potent antiplaque and antigingivitis properties when compared to placebo.

    Addition of probiotics to infant formula may positively affect immune function in nonexclusively breastfed infants. This study aimed to investigate the effect of infant starter formula containing the probiotic Bifidobacterium animalis subspecies lactis (Bb12) on intestinal immunity and inflammation. Six-week-old healthy, full-term infants (n = 172) were enrolled in a prospective, randomized, double-blind, controlled clinical trial with 2 groups studied in parallel to a breastfed comparison group. Formula-fed (FF) infants were randomized to partially hydrolyzed whey formula (CON) or the same formula containing 10(6) colony-forming units (CFU) Bb12/g (PRO) for 6 weeks. Fecal secretory IgA (sIgA), calprotectin, lactate, and stool pH were assessed at baseline, 2 weeks, and 6 weeks. Anti-poliovirus-specific IgA and anti-rotavirus-specific IgA were assessed at 2 and 6 weeks. Among vaginally delivered FF infants, PRO consumption increased (P IgA concentration increased (P IgA tended to increase (P = .056) with PRO consumption in cesarean-delivered infants. Anthropometrics and tolerance did not differ significantly between FF infants. Infants consuming formula with Bb12 produced feces with detectable presence of Bb12 and augmented sIgA concentration. Furthermore, cesarean-delivered infants consuming Bb12 had heightened immune response, as evidenced by increased anti-rotavirus- and anti-poliovirus-specific IgA following immunization. These results demonstrate that negative immune-related effects of not breastfeeding and cesarean delivery can be mitigated by including Bb12 in infant formula, thereby providing infants a safe, dietary, immune-modulating bacterial introduction.

    Full Text Available Background : The addition of clonidine to lidocaine intravenous regional anesthesia (IVRA has been previously reported to improve postoperative analgesia in patients undergoing upper extremity surgery. Our objective was to perform a dose ranging study in order to determine the optimal dose of clonidine used with lidocaine in IVRA. Design & Setting : We performed a double-blinded randomized placebo-controlled study with 60 patients scheduled for elective endoscopic carpal tunnel release under IVRA with 50 ml lidocaine 0.5%. University-affiliated outpatient surgery center. Data collected in operating rooms, recovery room, and by telephone after discharge from surgery center. Materials & Methods : Sixty adult ASA I or II patients undergoing outpatient endoscopic carpal tunnel release under intravenous regional anesthesia.Patients were randomized into five study groups receiving different doses of clonidine in addition to 50 ml 0.5% lidocaine in their IVRA. Group A received 0 mcg/kg, group B 0.25 mcg/kg, group C 0.5 mcg/kg, group D 1.0 mcg/kg and group E 1.5 mcg/kg of clonidine.Intraoperative fentanyl, recovery room pain scores, time to first postsurgical analgesic, total number of acetaminophen/codeine tablets consumed postsurgery, incidence of sedation, hypotension and bradycardia. Results & Conclusions : There was no benefit from any dose of clonidine compared to placebo. There were no clonidine-related side effects seen within the dose range studied. In short duration minor hand surgery, the addition of clonidine to lidocaine-based intravenous regional anesthesia provides no measurable benefit.

    Methadone and ketamine are used in neuropathic pain management. However, the benefits of both drugs association are uncertain in the treatment of neuropathic pain. Our primary objective was test the hypothesis that oral methadone combined with oral ketamine is more effective than oral methadone or ketamine alone in reducing neuropathic pain. We conducted a randomized, double blind, active-controlled parallel-group clinical trial. Forty-two patients with neuropathic pain refractory to conventional therapy were randomly assigned to receive oral methadone (n = 14), ketamine (n = 14), or methadone plus ketamine (n = 14) over a 3-month period. During these 90 days, we observed pain scores using a visual analogical scale (VAS), allodynia, burning/shooting pain, and some side effects. All treatments were effective in reducing pain scores by at least 40%. However, a significant improvement in pain was observed only in the ketamine alone group compared with both the methadone or methadone/ketamine groups. No significant differences were observed among the treatment groups for the reduction of burning or shooting pain, while ketamine alone was more effective than methadone or methadone/ketamine for the reduction of allodynia. Formal assessment for awareness of the allocation was not performed, some co-intervention bias may have occurred, our results could be only relevant to the patient population investigated and the use of VAS as the primary outcome detect changes in pain intensity but not to assess neuropathic pain symptoms. This study indicates that ketamine was better than methadone or methadone/ketamine for treating neuropathic pain.Key words: Multimodal analgesia, refractory pain, NMDA receptor, opioid.

    The role of electroacupuncture (EA) in reducing sedative and analgesic requirements during EUS is uncertain. The aim of the current study is to investigate the efficacy of EA in reducing procedure-related pain and discomfort during EUS. This was a double-blinded randomized controlled study conducted between March 2014 and July 2016. Consecutive patients who were scheduled for diagnostic EUS were recruited and randomized to receive electroacupuncture (EA) or sham-electroacupuncture (SA). The primary outcome was the dosage of propofol used. Other outcome measurements included pain scores, anxiety scores, satisfaction scores, patients' willingness to repeat the procedure, total procedure time, and adverse events. One hundred twenty-eight patients were recruited to the study. The patients that received EA had significantly fewer PCA requirements. The median (IQR range) number of demands for PCA (2 [1 - 5] vs 16.5 [8.5 - 33.8], P<0.001), the number of successful demands (2 [1 - 4] vs 9 [5.3 - 13], P<0.001), the total dose of propofol (0.15 [0.08 - 0.34] vs 0.77 [0.38 - 1.09], P<0.001) and alfentanil (0.38 [0.20 - 0.86] vs 1.92 [0.94 - 2.72], P<0.001) were all significantly less. Patients that received EA also had significantly less procedural pain scores and anxiety scores (P<0.001), higher satisfaction scores (P<0.001), and they are more willing to repeat the procedure (P<0.001). Both being in the SA group and the procedural time were significant predictors to increased PCA demands (P < 0.001 and P = 0.009 respectively). In conclusion, the use of EA reduced sedative and analgesic demands, improved patient experience, and was associated with low risk of adverse events during diagnostic EUS.

    Cerebrolysin showed neuroprotective and neurotrophic properties in various preclinical models of ischemia and small clinical trials. The aim of this large double-blind, placebo-controlled randomized clinical trial was to test its efficacy and safety in patients with acute ischemic stroke. Patients with acute ischemic hemispheric stroke were randomized within 12 hours of symptoms onset to active treatment (30 mL Cerebrolysin daily) or placebo (saline solution) given as intravenous infusion for 10 days in addition to aspirin (100 mg daily). The patients were followed up to 90 days. The primary end point was the result of a combined global directional test of modified Rankin Scale, Barthel Index, and National Institutes of Health Stroke Scale. Adverse events were documented to assess safety. A total of 1070 patients were enrolled in this study. Five hundred twenty-nine patients were assigned to Cerebrolysin and 541 to placebo. The confirmatory end point showed no significant difference between the treatment groups. When stratified by severity however, a post hoc analysis of National Institutes of Health Stroke Scale and modified Rankin Scale showed a trend in favor of Cerebrolysin in patients with National Institutes of Health Stroke Scale >12 (National Institutes of Health Stroke Scale: OR, 1.27; CI lower bound, 0.97; modified Rankin Scale: OR, 1.27; CI lower bound, 0.90). In this subgroup, the cumulative mortality by 90 days was 20.2% in the placebo and 10.5% in the Cerebrolysin group (hazard ratio, 1.9661; CI lower bound, 1.0013). In this study, the confirmatory end point showed neutral results between the treatment groups. However, a favorable outcome trend was seen in the severely affected patients with ischemic stroke treated with Cerebrolysin. This observation should be confirmed by a further clinical trial.

    Full Text Available Medical management is rapidly becoming a very im-portant part of the armamentarium of the urologist in-volved in the treatment of benign prostatic hyperplasia. The commonest options for medical management include alpha-blockers, 5-alpha reductase inhibitors, and pro-gestational anti-androgens. We present a double-blind randomized controlled trial evaluating the safety and efficacy of terazosin, finasteride and allylestrenol, the prototype drugs in each of these respective categories. A total of 140 patients who satisfied the inclusion and exclusion criteria were inducted into the trial after an informed consent. They were randomized into 4 groups, which received placebo, terazosin, finasteride and allylestrenol respectively for 6 months. Since 29 patients did not complete 6 months of therapy, there were 111 evaluable patients at the end of the study. We found that these 3 drugs produce comparable improvement in symp-tom score (-40%, flow rates (-60% and PVR (-50% which is significantly better than that in the placebo group. Both allylestrenol and finasteride bring about a comparable reduction in prostate volume (-23%, which is statistically significant as compared to the placebo and terazosin groups. Terazosin in doses of I and 2 mg/ day was, found to be effiective and well-tolerated in the vast majority of our cases. No adverse effects were seen in the placebo and finasteride groups, while 9.6% in the terazosin group had postural hypotension and 10.7% in the allylestrenol group had some loss of libido, prob-lems which were reversible upon cessation of therapy.

    Wear-induced osteolysis is the main factor in reducing the longevity of total hip arthroplasty (THA). The transmembrane Receptor Activator of Nuclear Factor κ B (RANK) and its corresponding ligand RANKL is an important regulator of osteoclast activity and bone resorption and is associated with osteolysis around implant. Inhibiting RANKL with denosumab is effective in vivo in preventing osteoporosis-related fractures. In vitro, osteoclasts can be blocked in animal models of osteolysis. We hypothesize that denosumab is effective in reducing wear-induced osteolysis around uncemented acetabular implants in THA. A randomized, double-blind, placebo-controlled trial will be conducted. We will include 110 patients, 40-85 years of age, with a known osteolytic lesion around an uncemented acetabular component ≥7 years after the primary operation. The patients will be randomized in a 1:1 ratio to subcutaneous injections of 60 mg denosumab or placebo for a total of 6 doses with start on day one and every 6 months with last treatment at 30 months. The primary endpoint will be the change in volume of the osteolytic lesion at 3 years measured with three-dimensional computed tomography (3D-CT). Secondary endpoints include functional outcome scores, change in bone mineral density of the lumbar spine, serological markers of bone turnover and adverse events. In vitro results of both bisphosphonates and RANKL inhibitors have been promising, showing reduced osteolysis with treatment. This is, to our knowledge, the first clinical trial testing the efficacy of denosumab in reducing wear-induced osteolysis. The study is an academic, phase II trial from an independent center and is designed to demonstrate efficacy in reducing volume of osteolytic lesions around a total hip arthroplasty.

    Some pregnant women discontinue iron supplements consumption due to Gastrointestinal (GI) complications, whereas pregnancy induces the same complications physiologically. The aim of the present study was to assess GI complications of ferrous sulfate in pregnant women. This randomized, double-blind, placebo-controlled clinical trial was performed on 176 pregnant women referred to prenatal care clinic of Maryam Hospital from April 2011 to February 2012. Pregnant women with Hb ≥ 13.2 gr/dL at 13(th) - 18(th) weeks of gestation were selected based on the inclusion criteria and were randomly assigned to the ferrous sulfate and placebo groups. The ferrous sulfate group (n = 90) received a 50-mg ferrous sulfate tablet daily from the 20(th) week to the end of pregnancy and the placebo group (n = 89) received one placebo tablet in the same way. All participants were visited twice at 24(th) - 28(th) and 32(nd) - 36(th) weeks to assess the GI complications as well as Hb level to determine the Hb changes in two groups. Chi-square test, t-test and Kolmogorov-Smirnov test were used to analyze the data. P value of ferrous sulfate and placebo groups at 24(th) - 28(th) and 32(nd) - 36(th) weeks. Hemoglobin drop lower than 10.5 gr/dL at 24(th) - 28(th) weeks or lower than 11 g/dL at 32(nd) - 36(th) weeks was not observed in any cases. It can be concluded that GI complications in pregnant women using ferrous sulfate are mostly caused by physiologic changes of pregnancy rather than ferrous sulfate; therefore, it is not reasonable to stop using ferrous sulfate due to GI complications.

    Despite increased prescription of a gluten-free diet for gastrointestinal symptoms in individuals who do not have celiac disease, there is minimal evidence that suggests that gluten is a trigger. The aims of this study were to determine whether gluten ingestion can induce symptoms in non-celiac individuals and to examine the mechanism. A double-blind, randomized, placebo-controlled rechallenge trial was undertaken in patients with irritable bowel syndrome in whom celiac disease was excluded and who were symptomatically controlled on a gluten-free diet. Participants received either gluten or placebo in the form of two bread slices plus one muffin per day with a gluten-free diet for up to 6 weeks. Symptoms were evaluated using a visual analog scale and markers of intestinal inflammation, injury, and immune activation were monitored. A total of 34 patients (aged 29-59 years, 4 men) completed the study as per protocol. Overall, 56% had human leukocyte antigen (HLA)-DQ2 and/or HLA-DQ8. Adherence to diet and supplements was very high. Of 19 patients (68%) in the gluten group, 13 reported that symptoms were not adequately controlled compared with 6 of 15 (40%) on placebo (P=0.0001; generalized estimating equation). On a visual analog scale, patients were significantly worse with gluten within 1 week for overall symptoms (P=0.047), pain (P=0.016), bloating (P=0.031), satisfaction with stool consistency (P=0.024), and tiredness (P=0.001). Anti-gliadin antibodies were not induced. There were no significant changes in fecal lactoferrin, levels of celiac antibodies, highly sensitive C-reactive protein, or intestinal permeability. There were no differences in any end point in individuals with or without DQ2/DQ8. "Non-celiac gluten intolerance" may exist, but no clues to the mechanism were elucidated.

    An estimated 15% of patients with diabetes will develop a foot ulcer sometime in their life, making them 30 to 40 times more likely to undergo amputation due to a non-healing foot ulcer than the non-diabetic population. To determine the safety and efficacy of a new, non-contact, kilohertz ultrasound therapy for the healing of recalcitrant diabetic foot ulcers - as well as to evaluate the impact on total closure and quantitative bacterial cultures and the effect on healing of various levels of sharp/surgical debridement - a randomized, double-blinded, sham-controlled, multicenter study was conducted in hospital-based and private wound care clinics. Patients (55 met criteria for efficacy analysis) received standard of care, which included products that provide a moist environment, offloading diabetic shoes and socks, debridement, wound evaluation, and measurement. The "therapy" was either active 40 KHz ultrasound delivered by a saline mist or a "sham device" which delivered a saline mist without the use of ultrasound. After 12 weeks of care, the proportion of wounds healed (defined as complete epithelialization without drainage) in the active ultrasound therapy device group was significantly higher than that in the sham control group (40.7% versus 14.3%, P = 0.0366, Fisher's exact test). The ultrasound treatment was easy to use and no difference in the number and type of adverse events between the two treatment groups was noted. Of interest, wounds were debrided at baseline followed by a quantitative culture biopsy. The results of these cultures demonstrated a significant bioburden (greater than 10(5)) in the majority of cases, despite a lack of clinical signs of infection. Compared to control, this therapeutic modality was found to increase the healing rate of recalcitrant, diabetic foot ulcers.

    The beneficial effects of probiotics are now widely reported, although there are only a few studies on their anti-aging effects. We have found that Lactobacillus plantarum HY7714 (HY7714) improves skin hydration and has anti-photoaging effects, and in the present study, we have further evaluated the anti-aging effect of HY7714 via a randomized, double blind, placebo-controlled clinical trial. The trial included 110 volunteers aged 41 and 59 years who have dry skin and wrinkles. Participants took 1 × 10(10) CFU/day of HY7714 (probiotic group) or a placebo (placebo group) for 12 weeks. Skin hydration, wrinkles, skin gloss, and skin elasticity were measured every 4 weeks during the study period. There were significant increases in the skin water content in the face (p < 0.01) and hands (p < 0.05) at week 12 in the probiotic group. Transepidermal water loss decreased significantly in both groups at weeks 4, 8, and 12 (p < 0.001 compared with baseline), and was suppressed to a greater extent in the face and forearm in the probiotic group at week 12. Volunteers in the probiotic group had a significant reduction in wrinkle depth at week 12, and skin gloss was also significantly improved by week 12. Finally, skin elasticity in the probiotic group improved by 13.17% (p < 0.05 vs. controls) after 4 weeks and by 21.73% (p < 0.01 vs. controls) after 12 weeks. These findings are preliminary confirmation of the anti-aging benefit to the skin of L. plantarum HY7714 as a nutricosmetic agent.

    The present study was carried out to examine this hypothesis that administration of selenium can prevent the development of injuries by brain trauma and thus can modulate patients' functional recovery and also improve posttraumatic outcome. This double-blinded controlled trial was carried out on 113 patients who were hospitalized following traumatic brain injury (TBI) with Glasgow Coma Scale score of 4-12 that were randomly assigned to receive selenium within 8 h after injury plus standard treatment group or routine standard treatment alone as the control. The primary endpoint was to assess patients' functional recovery at 2 months after the injury based on extended Glasgow Outcome Scale score (GOS-E). Secondary outcomes included the changes in Full Outline of Unresponsiveness score (FOUR) score, Sequential Organ Failure Assessment (SOFA) score, and acute physiology and chronic health evaluation (APACHE) III score, side effects of selenium, length of Intensive Care Unit (ICU) stay, and length of hospital stay. There was no difference in the length of ICU and hospital stay, the trend of the change in FOUR and SOFA scores within 15 days of first interventions, and the mean APACHE III score on the 1(st) and 15(th) days between the two groups. Mortality was 15.8% in selenium group and 19.6% in control group with no between-group difference. No difference was revealed between the two groups in appropriate outcome according to GOS-E score at 60 ± 10 days and also 30 ± 5 days according to the severity of TBI. This human trial study could not demonstrate beneficial effects of intravenous infusion of selenium in the improvement of outcomes in patients with acute TBI.

    Full Text Available Introduction. Pain is the commonest morbidity after open surgical procedures. The most effective treatment of postoperative pain is opioid therapy. Morphine, the commonly used opioid, is associated with many side effects including respiratory depression, sedation, postoperative nausea vomiting, and pruritus. Nalbuphine, on the other hand, is known to cause less respiratory depression. Thus this study was undertaken to compare the intraoperative and postoperative analgesic efficacy and side effect profile of the two drugs. Methodology. 60 patients undergoing open gynaecological surgery were randomized to receive either morphine (Group M or nalbuphine (Group N in the intraoperative and postoperative period. Intraoperative analgesic efficacy (measured by need for rescue analgesics, postoperative pain by visual analogue scale, and side effects like postoperative nausea, vomiting, sedation, respiratory depression, and pruritus were compared in both groups. Intraoperative and postoperative heart rate and blood pressure were also compared between the groups. Results. Need for intraoperative analgesia was significantly more in Group N (P=0.023. Postoperative VAS scores were significantly different between the groups at various time points; however, none of the patients required any rescue analgesia. The incidence of various side effects was not significantly different between the groups. The haemodynamic profile of patients was comparable between the groups in both intraoperative and postoperative period. Conclusion. Nalbuphine provides less effective intraoperative analgesia than morphine in patients undergoing open gynaecological surgery under general anaesthesia. Both drugs, however, provided similar postoperative analgesia and had similar haemodynamic and side effect profile.

    Full Text Available Fifty renal transplant patients were randomized to receive either 800 mg acyclovir by mouth four times daily or identical placebo tablets for prophylaxis of herpes simplex infection. Patients were followed weekly to assess reactivation of herpes simplex, varicella zoster virus, Epstein-Barr virus or cytomegalovirus (CMV infections. The patients received standard immunosuppressive regimens including cyclosporine A. Acyclovir suppressed secretion of herpes simplex virus in treated patients (P=0.001. Three episodes of mucocutaneous herpes simplex virus occurred in placebo recipients and one in a noncompliant acyclovir recipient. A clinically important difference in graft survival was demonstrated, but because of sample size failed to reach statistical significance (P=0.11. No reactivation of varicella zoster virus, Epstein-Barr virus or CMV infection was detected in either group. Toxicity was limited to central nervous irritability. The authors conclude that high dose oral acyclovir provides effective prophylaxis for prevention of herpes simplex virus infections in renal transplantation and may be associated with increased graft survival, perhaps from suppression of CMV infection.

    Full Text Available "nVarious studies suggest that selective serotonin reuptake inhibitors (SSRIs may be useful in treating pathological skin picking (PSP. This study sought to assess effectiveness of citalopram in comparison with placebo in treating PSP. Forty five individuals with PSP were recruited in a four-week, randomized clinical trial of citalopram (20 mg/day in comparison with placebo. Study measures assessing skin picking severity, mental health status, obsessive compulsive disorder and quality of life were given at baseline, weeks 2 and 4. PSP severity, general health status, obsession-compulsion severity and quality of life level were similar between two groups at baseline (P > 0.05. Treatment analyses revealed significant improvements in quality of life, general health status and obsession-compulsion severity in citalopram group compared to placebo group (P < 0.05. Mean PSP severity reduction in citalopram group was more than placebo group but this difference was not significant. Citalopram can improve general health status and quality of life in individuals with PSP but its effect on skin picking behavior doesn't differ significantly with placebo. Other trials with longer time are needed to determine the exact efficacy of citalopram on PSP

    The aim of this study was to assess the effect of ondansetron on symptoms of patients with subjective tinnitus accompanied by sensorineural hearing loss or normal hearing. Sixty patients with a chief complaint of tinnitus (with duration of more than 3 months) were equally randomized to ondansetron or placebo for 4 weeks. The dose of ondansetron was gradually increased from 4 mg/day (one tablet) to 16 mg/day (4 tablets) during 12 days and then continued up to 4 weeks. The exact number of tablets was prescribed in the placebo group. Patients underwent audiologic examinations and filled questionnaires at baseline and after 4 weeks of treatment. Our primary outcomes were changes in Tinnitus Handicap Inventory questionnaire (THI), Tinnitus Severity Index (TSI) and visual analog scale (VAS) scores. Our secondary outcomes were the changes in depression and anxiety based on Hospital Anxiety and Depression (HADS) questionnaire, side effects, tinnitus loudness matching, tinnitus pitch matching, pure tone audiometry and speech recognition threshold (SRT). In the ondansetron and placebo groups, 27 and 26 patients completed the study, respectively. The changes in VAS (P = 0.934), THI (P = 0.776), anxiety (P = 0.313) and depression (P = 0.163) scores were not different between the groups. TSI score decreased significantly in the ondansetron compared with the placebo group (P = 0.004). Changes in tinnitus loudness matching (P = 0.75) and pitch matching (P = 0.56) did not differ between the two groups. Ondansetron, but not placebo, decreased the SRT threshold (right, P tinnitus hypothetically through cochlear amplification.

    Conditioned pain modulation (CPM) is widely used to measure endogenous analgesia, and a recent study indicated that drugs that act on endogenous analgesia are more effective in individuals with lower CPM. Recent animal studies have indicated that pregabalin activates endogenous analgesia by stimulating the descending pain inhibitory system. The present study examined whether the analgesic effect of pregabalin is greater in individuals with lower original endogenous analgesia using CPM. Fifty-nine healthy subjects were randomly assigned to either a pregabalin group or a placebo group, and 50 of them completed the study. CPM was measured before and after pregabalin or placebo administration. The correlation of initial CPM to change in CPM was compared between the pregabalin and placebo groups. Initial CPM was significantly correlated with the change in CPM in the pregabalin group (r = -0.73, p < 0.0001) but not in the placebo group (p = 0.56) (difference in correlation coefficients between groups; p = 0.004). Furthermore, the initial CPM significantly affected the change in CPM in the pregabalin group but not in the placebo group (pregabalin group: adj R(2)  = 0.51, p < 0.001, y = -0.54x + 2.98; placebo group: p = 0.56, significant difference in regression slopes; p = 0.015). These results indicate that pregabalin has a higher endogenous analgesic effect in individuals with lower original endogenous analgesia. The analgesic effect of pregabalin depends on the original endogenous analgesia status. Its effect on conditioned pain modulation (CPM) was stronger for subjects with lower original endogenous analgesia, suggesting that the mechanism of pregabalin involves the improvement of endogenous analgesia. © 2017 European Pain Federation - EFIC®.

    To assess the impact of pre-procedural remote ischemic preconditioning on the incidence of myocardial complications following percutaneous coronary intervention. Ischemic preconditioning of a remote vascular territory improves the subsequent ischemic tolerance of distant organs. The Myocardial Event Reduction with Ischemic Preconditioning Therapy (MERIT) trial recruited 80 consecutive patients undergoing elective angioplasty with drug-eluting stents to receive two 5-min lower limb tourniquet occlusions or an un-inflated tourniquet (controls) 1 h before the procedure. The primary outcome was troponin T level at 24 h. Secondary outcomes were intra-procedural chest pain and ST-segment deviation. 6 patients in the control group and 2 in the ischemic preconditioning group had pre-procedural raised troponin T (p = 0.23). This increased to 16 (40%) in the control group and 5 (12.5%) in the study group at 24 h (p = 0.01). Fewer patients in the study group experienced intra-procedural chest pain (1 vs. 7, p = 0.056). Mean ST-segment deviation time was 13 ± 35 s in the study group and 58 ± 118 s in the control group (p = 0.02). At a mean follow-up of 11 months, the major adverse cardiac event rate did not differ significantly between the groups. These data suggest that ischemic preconditioning reduces the absolute risk of post-procedure cardiomyocyte necrosis by 27.5%, and reduces intra-procedural chest pain and ST-segment deviation in patients undergoing percutaneous coronary interventions. We suggest its routine use in percutaneous coronary intervention, although the long-term prognostic impact in this patient group warrants further investigation.

This was an equally randomized, double-blind, placebo-controlled, parallel-group, single center trial. Adult patients undergoing laparoscopic fundoplication were recruited. The intervention group received 1 mg/kg intravenous lidocaine bolus prior to induction of anesthesia, then an intravenous infusion at 2 mg/kg/h for 24 hours. The primary outcome was pain, measured using a numeric rating scale for 30 hours postoperatively. Secondary outcomes were nausea and vomiting, opioid requirements, adverse events, serum lidocaine concentration, and length of hospital stay. The study was terminated after an interim analysis of 24 patients showed evidence of futility. There was no difference in postoperative pain scores (lidocaine versus control, mean ± standard deviation at rest (2.0 ± 2.7 vs 2.1 ± 2.4, P=0.286 or with movement (2.0 ± 2.6 vs 2.6 ± 2.7, P=0.487. Three adverse events occurred in the lidocaine group (25% of patients. Intravenous lidocaine did not provide clinically significant analgesia to patients undergoing laparoscopic fundoplication.

    Full Text Available Abstract Background Natural rubber latex allergy is a common and unsolved health problem. Since the avoidance of exposure is very difficult, immunotherapy is strongly recommended, but before its use in patients, it is essential to prove the efficacy and safety of extracts. The aim of the present randomised, double-blind, placebo-controlled clinical trial was to assess the efficacy and tolerability of latex sublingual immunotherapy in adult patients undergoing permanent latex avoidance. Methods Twenty-eight adult latex-allergic patients (5 males and 23 females, with mean age of 39 years (range 24-57 were randomized to receive a commercial latex-sublingual immunotherapy or placebo during one year, followed by another year of open, active therapy. The following outcomes were measured at baseline and at the end of first and second year of follow-up: skin prick test, gloves-use score, conjunctival challenge test, total and specific IgE, basophil activation test, and adverse reactions monitoring. Results No significant difference in any of the efficacy in vivo variables was observed between active and placebo groups at the end of the placebo-controlled phase, nor when each group was compared with their baseline values at the end of the two year-study. An improvement in the average percentage of basophils activated was observed. During the induction phase, 4 reactions in the active group and 5 in the placebo group were recorded. During the maintenance phase, two patients dropped out due to pruritus and to acute dermatitis respectively. Conclusion Further studies are needed to evaluate latex-sublingual immunotherapy, since efficacy could not be demonstrated in adult patients with avoidance of the allergen.

    We compared the efficacy of melatonin and placebo as adjuvants in the withdrawal of patients from long term temazepam, zopiclone or zolpidem (here 'BZD') use. A double-blind, placebo-controlled, randomized trial was conducted in a primary health care outpatient clinic. Ninety-two men or women (≥55 years) with primary insomnia and chronic BZD use received controlled release melatonin 2 mg (CRM) (n = 46) or placebo (n = 46) during the 1 month withdrawal from BZDs. Psychosocial support was provided. Follow-up continued for up to 6 months. Successful BZD withdrawal by the end of 1 month was confirmed by BZD plasma determinations, while reduction in BZD use and abstinence continuing for 6 months were noted. There were two drop-outs on CRM and one on placebo. After a 1 month withdrawal, 31 participants (67%; 95% CI 54, 81) on CRM and 39 (85%; 74, 95) on placebo had withdrawn completely (intention-to-treat analysis between groups, P = 0.051; per protocol P = 0.043). Reduction in BZD use was similar or even more rare in the CRM than in the placebo group (P = 0.052 per protocol). After 6 months, 14 participants in the CRM group and 20 in the placebo group remained non-users of BZD (NS between groups). BZD doses were higher in the CRM than in the placebo group at the end of the 6 month follow-up (P = 0.025). Withdrawal symptoms did not differ between the groups. Gradual dose reduction of BZDs combined with CRM or placebo, and psychosocial support produced high short term and moderate long term BZD abstinence. CRM showed no withdrawal benefit compared with placebo. © 2013 The British Pharmacological Society.

    Chronic pain related to postoperative abdominal adhesions is a common problem with no standard analgesic regimen currently established. In a double-blind, placebo-controlled trial, we examined the effects of pregabalin on pain modulation in patients with prior abdominal surgery and documented adhesion. The primary outcome measure was pain relief documented by a 2-point change on the Likert pain scale with a secondary pain measure of sleep interruption. A total of 18 women were randomized to receive either the drug (n = 11) or placebo (n = 7). Thirteen patients (eight pregabalin, five placebo) completed the blinded phase and 10 patients (seven pregabalin, three placebo) completed the open-label phase. Statistical analysis was performed in two settings: 1) Week 0 (as the baseline) through the end of Week 7 of the blinded fixed-dose phase; and 2) Week 7 (as the baseline) along With weeks 8 through 11 of the open-label phase. The pain score result from the blinded phase setting indicated that the amount of decrease was significantly greater in the drug group (P = 0.024), whereas the pain score result from the open-label setting indicated that the amount of decrease was significantly greater in the placebo group (P = 0.043). Only the sleep score result in the open-label setting was significantly greater in the placebo group (P = 0.024). We conclude that pregabalin significantly reduced patient-documented pain scores compared with placebo in our small cohort of patients with abdominal adhesion pain.

    Crataegus laevigata is a medicinal plant most commonly used for the treatment of heart failure and psychosomatic disorders. Based on previous experimental findings, this double-blind placebo-controlled study was aimed at finding beneficial effects of C. laevigata on biomarkers of coronary heart disease (CHD). The study included 49 diabetic subjects with chronic CHD who were randomly assigned to the treatment for 6 months with either a micronized flower and leaf preparation of C. laevigata (400 mg three times a day) or a matching placebo. Blood cell count, lipid profile, C-reactive protein, neutrophil elastase (NE) and malondialdehyde were analyzed in plasma at baseline, at one month and six months. The main results were that NE decreased in the C. laevigata group compared to the placebo group. In the C. laevigata group, baseline figures (median and interquartile range) were 35.8 (4.5) and in the placebo group 31 (5.9). At the end of the study, values were 33.2 (4.7) ng/ml and 36.7 (2.2) ng/ml, respectively; plaevigata, added to statins, decreased LDL cholesterol (LDL-C) (mean±SD) from 105±28.5 mg/dl at baseline to 92.7±25.1 mg/dl at 6 months (p=0.03), and non-HDL cholesterol from 131±37.5 mg/dl to 119.6±33 mg/dl (plaevigata decreased NE and showed a trend to lower LDL-C compared to placebo as add-on-treatment for diabetic subjects with chronic CHD.

    The incidence of hypokalemia in continuous ambulatory peritoneal dialysis (CAPD) patients is about 15-60%, leading to significant complications. There is no standard treatment other than potassium supplement in this setting. The aim of this study was to evaluate effect of spironolactone 25 mg/day in CAPD patients who have a history of hypokalemia. This is a randomized, double-blind, placebo-controlled, cross-over study in CAPD patients who had a history of hypokalemia. Study intervention is 4 weeks of oral spironolactone 25 mg/day or placebo, cross-over after a 2-week wash-out period. The primary outcome was the difference of serum potassium before and after 4 weeks of spironolactone treatment. Serum potassium was measured every 2 weeks, serum magnesium, urine and peritoneal fluid potassium measured before and after each treatment period. We enrolled 24 patients, and 20 completed the cross-over study. Ten patients were anuric. The total doses of potassium supplement were the same during the study period. Serum potassium levels before and after study intervention were not significantly different in both groups (4.23 ± 0.64 vs. 3.90 ± 0.59 mEq/L for spironolactone P = 0.077 and 3.84 ± 0.62 vs. 3.91 ± 0.52 for placebo P = 0.551). Total 24-h potassium, magnesium, sodium excretion, urine volume and ultrafiltration volume were not affected by spironolactone or placebo. There was one episode of hyperkalemia (5.6 mEq/L) during the spironolactone treatment period. Spironolactone 25 mg/day does not have a significant effect on serum potassium or urine and peritoneal excretion rate in CAPD patients who have a history of hypokalemia.

    Full Text Available Context Glutamine is the main source of energy of the enterocyte and diarrhea and weight loss are frequent in HIV infected patients. Objective To determine the effect of alanyl-glutamine supplementation on intestinal permeability and absorption in these patients. Methods Randomized double-blinded, placebo-controlled study using isonitrogenous doses of alanyl-glutamine (24 g/day and placebo (glycine, 25 g/day during 10 days. Before and after this nutritional supplementation lactulose and mannitol urinary excretion were determined by high performance liquid chromatography. Results Forty six patients with HIV/AIDS, 36 of whom were male, with 37.28 ± 3 (mean ± standard error years were enrolled. Twenty two and 24 subjects were treated with alanyl-glutamine and with glycine respectively. In nine patients among all in the study protocol that reported diarrhea in the 14 days preceding the beginning of the study, mannitol urinary excretion was significantly lower than patients who did not report this symptom [median (range: 10.51 (3.01–19.75 vs. 15.37 (3.93–46.73; P = 0.0281] and lactulose/mannitol ratio was significantly higher [median (range: 0.04 (0.00–2.89 vs. 0.02 (0.00–0.19; P = 0.0317]. There was also a significant increase in mannitol urinary excretion in the group treated with alanyl-glutamine [median (range: 14.38 (8.25–23.98 before vs 21.24 (6.27–32.99 after treatment; n = 14, P = 0.0382]. Conclusion Our results suggest that the integrity and intestinal absorption are more intensely affected in patients with HIV/AIDS who recently have had diarrhea. Additionally, nutritional supplementation with alanyl-glutamine was associated with an improvement in intestinal absorption.

    One-third of the total population seems to develop minor recurrent aphthous stomatitis (RAS) during their lifetime. However, well-controlled dietary intervention studies to prevent minor RAS are very rare. The objective of the present study was to investigate whether the prevalence of RAS decreased with perilla oil (rich in alpha-linolenic acid). Thirty subjects (8 men and 22 women) who had minor RAS at least once a month were randomly allocated to a soybean oil group or a perilla oil group in a double-blind manner (experimental phase) after a run-in phase of 4 mo during which subjects used a reference oil, the most popular cooking oil in Japan, or a 50/50 mixture of soybean oil and rapeseed oil. During the experimental phase, subjects were asked to use soybean oil or perilla oil as the sole cooking oil for 8 mo. Blood samples were collected at the start and end of the experimental phase for fatty acid analysis of total plasma phospholipid fraction. Occurrence and needed days for healing of minor RAS were recorded during the two phases and compared. alpha-Linolenic acid concentrations in the plasma phospholipid fraction increased significantly in both groups during the experimental phase to a similar extent. The prevalence of minor RAS in the experimental phase decreased significantly in both groups compared with the run-in phase to a similar extent, without intergroup differences. Perilla oil, which is rich in alpha-linolenic acid, was not superior to soybean oil in preventing minor RAS. There was a possibility that avoiding rapeseed oil might be beneficial for prevention of minor RAS.

    Subfebrile body temperature and fever in the first days after stroke are strongly associated with unfavorable outcome. A subgroup analysis of a previous trial suggested that early treatment with paracetamol may improve functional outcome in patients with acute stroke and a body temperature of ≥36.5°C. In the present trial, we aimed to confirm this finding. PAIS 2 (Paracetamol [Acetaminophen] in Stroke 2) was a multicenter, randomized, double-blind, placebo-controlled clinical trial. We aimed to include 1500 patients with acute ischemic stroke or intracerebral hemorrhage within 12 hours of symptom onset. Patients were treated with paracetamol in a daily dose of 6 g or matching placebo for 3 consecutive days. The primary outcome was functional outcome at 3 months, assessed with the modified Rankin Scale and analyzed with multivariable ordinal logistic regression. Because of slow recruitment and lack of funding, the study was stopped prematurely. Between December 2011 and October 2015, we included 256 patients, of whom 136 (53%) were allocated to paracetamol. In this small sample, paracetamol had no effect on functional outcome (adjusted common odds ratio, 1.15; 95% confidence interval, 0.74-1.79). There was no difference in the number of serious adverse events (paracetamol n=35 [26%] versus placebo n=28 [24%]). Treatment with high-dose paracetamol seemed to be safe. The effect of high-dose paracetamol on functional outcome remains uncertain. Therefore, a large trial of early treatment with high-dose paracetamol is still needed. URL: http://www.trialregister.nl.

    Full Text Available Japanese encephalitis (JE virus (JEV is a mosquito-borne flavivirus found across Asia that is closely related to West Nile virus. There is no known antiviral treatment for any flavivirus. Results from in vitro studies and animal models suggest intravenous immunoglobulin (IVIG containing virus-specific neutralizing antibody may be effective in improving outcome in viral encephalitis. IVIG's anti-inflammatory properties may also be beneficial.We performed a pilot feasibility randomized double-blind placebo-controlled trial of IVIG containing anti-JEV neutralizing antibody (ImmunoRel, 400mg/kg/day for 5 days in children with suspected JE at two sites in Nepal; we also examined the effect on serum neutralizing antibody titre and cytokine profiles. 22 children were recruited, 13 of whom had confirmed JE; 11 received IVIG and 11 placebo, with no protocol violations. One child (IVIG group died during treatment and two (placebo subsequently following hospital discharge. Overall, there was no difference in outcome between treatment groups at discharge or follow up. Passive transfer of anti-JEV antibody was seen in JEV negative children. JEV positive children treated with IVIG had JEV-specific neutralizing antibody titres approximately 16 times higher than those treated with placebo (p=0.2, which was more than could be explained by passive transfer alone. IL-4 and IL-6 were higher in the IVIG group.A trial of IVIG for JE in Nepal is feasible. IVIG may augment the development of neutralizing antibodies in JEV positive patients. IVIG appears an appealing option for JE treatment that warrants further study.ClinicalTrials.gov NCT01856205.

    Full Text Available Objective:Constipation is a common problem in children. There is some clinical evidence for the role of probiotics and prebiotics in the treatment of constipated children. This is the first study on the therapeutic effect of synbiotics (combination of probiotics and prebiotic in treatment of childhood constipation. Methods:In a double-blind randomized placebo controlled study 102 children aged 4-12 years with functional constipation were assessed according to Rome III criteria for 4 weeks. They were divided into 3 groups: Group A, received 1.5 ml/kg/day oral liquid paraffin plus placebo, group B, 1 sachet synbiotic per day plus placebo and group C, 1.5 ml/kg/day oral liquid paraffin plus 1 sachet synbiotic per day. Frequency of bowel movements (BMs, stool consistency, number of fecal incontinence episodes, abdominal pain, painful defecation per week, success of treatment and side effects were determined in each group before and after treatment. Findings:The frequency of BMs per week increased in all groups (P<0.001, but it differed between groups and was higher in group C (P=0.03. Stool consistency increased and number of fecal incontinence episodes, abdominal pain and painful defecation per week decreased in all groups similarly and there was statistically no difference between them. No side effects were reported in group B; the main side effect in group A and C was seepage of oil (P<0.001. Treatment success was similar in all groups without any significant difference between them (P=0.6.   Conclusion:This study showed that synbiotics have positive effects on symptoms of childhood constipation without any side effects.

    Mirtazapine added to antipsychotics appears to improve the clinical picture of schizophrenia, including both negative and positive symptoms. This study explored the effect of adjunctive mirtazapine on neurocognition in patients with schizophrenia who had shown an insufficient response to first-generation antipsychotics (FGAs). Thirty-seven schizophrenia patients, who were at least moderately ill despite their FGA treatment, received add-on mirtazapine (n=19) or placebo (n=18) in a 6-wk double-blind, randomized trial. Widely used neuropsychological tests were performed to explore visual-spatial functions, verbal and visual memory, executive functions, verbal fluency and general mental and psychomotor speed. The data were analysed on the modified intent-to-treat basis with last observation carried forward. False discovery rate was applied to correct for multiple testing. Mirtazapine outperformed placebo in the domains of visual-spatial ability and general mental speed/attentional control as assessed by, correspondingly, Block Design and Stroop dots. The difference in the degree of change (i.e. change while on mirtazapine minus that on placebo) was 18.6% (p=0.044) and 11.1% (p=0.044), respectively. Adjunctive mirtazapine might offer a safe, effective and cost-saving option as a neurocognitive enhancer for FGA-treated schizophrenia patients. Mirtazapine+FGA combinations may become especially useful in light of the currently increasing attention towards FGAs. Larger and longer studies that incorporate functional outcomes, as well as comparisons with second-generation antipsychotics are, however, still needed for more definite conclusions.

    Objectives Host iron availability is fundamental to mucormycosis pathogenesis. The combination of liposomal amphotericin B (LAmB) and deferasirox iron chelation therapy synergistically improved survival in diabetic mice with mucormycosis. To determine the safety of combination deferasirox plus LAmB therapy for mucormycosis, a multicentred, placebo-controlled, double-blinded clinical trial was conducted. Methods Twenty patients with proven or probable mucormycosis were randomized to receive treatment with LAmB plus deferasirox (20 mg/kg/day for 14 days) or LAmB plus placebo (NCT00419770, clinicaltrials.gov). The primary analyses were for safety and exploratory efficacy. Results Patients in the deferasirox arm (n = 11) were more likely than those in the placebo arm (n = 9) to have active malignancy, neutropenia and corticosteroid therapy, and were less likely to receive concurrent non-study antifungal therapy. Reported adverse events and serious adverse events were similar between the groups. However, death was more frequent in the deferasirox than in the placebo arm at 30 days (45% versus 11%, P = 0.1) and 90 days (82% versus 22%, P = 0.01). Global success (alive, clinically stable, radiographically improved) for the deferasirox arm versus the placebo arm at 30 and 90 days, respectively, was 18% (2/11) versus 67% (6/9) (P = 0.06) and 18% (2/11) versus 56% (5/9) (P = 0.2). Conclusions Patients with mucormycosis treated with deferasirox had a higher mortality rate at 90 days. Population imbalances in this small Phase II study make generalizable conclusions difficult. Nevertheless, these data do not support a role for initial, adjunctive deferasirox therapy for mucormycosis. PMID:21937481

    Full Text Available Introduction. L-Acetylcarnitine (LAC, the acetyl ester of carnitine naturally present in the central nervous system and involved in several neural pathways, has been demonstrated to be active in various animal experimental models resembling some features of human depression. The aim of the study is to verify whether LAC can have an antidepressant action in a population of elderly patients with dysthymic disorder in comparison with a traditional antidepressant such as fluoxetine.Methods. Multicentric, double-blind, double-dummy, controlled, randomized study based on a observation period of 7 weeks. 80 patients with DSM-IV diagnosis of dysthymic disorder were enrolled in the study and subdivided into 2 groups. Group A patients received LAC plus placebo; group B patients received fluoxetine 20 mg/die plus placebo. Clinical assessment was performed through several psychometric scales at 6 different moments.Results. Group A patients showed a statistically significant improvement in the following scales: HAM-D, HAM-A, BDI and Touluse–Pieron Test. Comparison between the two groups, A and B, generally showed very similar clinical progression.Discussion. The results obtained with LAC and fluoxetine were equivalent. As the subjects in this study were of senile age, it is possible to hypothesize that the LAC positive effect on mood could be associated with improvement in subjective cognitive symptomatology. The difference in the latency time of clinical response (1 week of LAC treatment, compared with the 2 weeks' latency time with fluoxetine suggests the existence of different mechanisms of action possibly in relation to the activation of rapid support processes of neuronal activity.

    To study the efficacy and safety of tolperisone--a centrally acting muscle relaxant with membrane stabilizing activity--in the treatment of stroke-related spasticity. This was a randomized, double-blind, placebo-controlled, multicenter study with parallel groups. Treatment lasted 12 weeks and was started with a titration period of variable length (dose range 300-900 mg tolperisone daily). The degree of spasticity determined on the Ashworth Scale in the most severely affected joint area was denned as primary target parameter. Hundred and twenty patients (43 females, 77 males) in a mean age of 63,3 +/- 10,6 years were recruited and received treatment. In the majority of patients both limbs of each side were affected by the spasticity which on average had been present for 3,3 +/- 4,4 years. A 62% of the patients were treated with a daily dose >600 mg tolperisone. Tolperisone reduced the mean Ashworth Score by a mean of 1,03 +/- 0,71 compared with a mean reduction of 0,47 +/- 0,54 in the placebo group (ptolperisone versus 45% of the placebo patients experienced a reduction by at least 1 point on the Ashworth Scale (ptolperisone. Adverse events occurred less often on active treatment (n=19) than on placebo (n=26) and were mostly of mild-to-moderate intensity. No withdrawals caused by adverse events were reported in the tolperisone group. The findings of the present study demonstrate the efficacy and excellent tolerance of tolperisone in the treatment of spastic hypertonia following cerebral stroke. Study data further suggest that an individual dose titration which may exceed the recommended maximum dose of 450 mg daily results in optimized therapeutic benefit.

    This study aimed to examine the efficacy of creatine supplementation, associated or not with resistance training, in vulnerable older women. A 24-week, double-blind, randomized, placebo-controlled trial was performed. Sixty subjects were assigned to compose the following groups: placebo (PL), creatine supplementation (CR), placebo with resistance training (PL+RT), and creatine supplementation with resistance training (CR+RT). The subjects were assessed at baseline and after 24weeks. The primary outcome was muscle strength, as assessed by one-repetition maximum (1-RM) tests. Secondary outcomes included appendicular lean mass, bone mass, biochemical bone markers, and physical function tests. The changes in 1-RM leg press were significantly greater in the CR+RT group (+19.9%) than in the PL (+2.4%) and the CR groups (+3.7%), but not than in the PL+RT group (+15%) (p=0.002, p=0.002, and p=0.357, respectively). The CR+RT group showed superior gains in 1-RM bench press (+10%) when compared with all the other groups (p≤0.05). The CR+RT group (+1.31%) showed greater appendicular lean mass accrual than the PL (-1.2%), the CR (+0.3%), and the PL+RT groups (-0.2%) (p≤0.05). The CR and the PL+RT groups experienced comparable gains in appendicular lean mass (p=0.62), but superior to those seen in the PL group. Changes in fat mass, bone mass and serum bone markers did not significantly differ between the groups (p>0.05). In conclusion, creatine supplementation combined with resistance training improved appendicular lean mass and muscle function, but not bone mass, in older vulnerable women.

    Physical fitness is a fundamental prerequisite for soccer players. Kaempferia parviflora is an herbal plant that has been used in some Asian athletes with the belief that it might prevent fatigue and improve physical fitness. This study aimed to determine the effects of Kaempferia parviflora on the physical fitness of soccer players. Sixty soccer players who routinely trained at a sports school participated in a double-blind placebo-controlled trial and were randomly allocated to the treatment group or the placebo group. The participants in both groups were given either 180 mg of Kaempferia parviflora extract in capsules or a placebo once daily for 12 weeks. Baseline data were collected using the following 6 tests of physical performance: a sit-and-reach test, a hand grip strength test, a back-and-leg strength test, a 40-yard technical test, a 50-metre sprint test, and a cardiorespiratory fitness test. All of the tests were performed every 4 weeks throughout the 12-week study period. The study showed that after treatment with Kaempferia parviflora, the right-hand grip strength was significantly increased at weeks 4, 8, and 12. The left-hand grip strength was significantly increased at week 8. However, the back-and-leg strength, the 40-yard technical test, the sit-and-reach test, the 50-metre sprint test, and the cardiorespiratory fitness test results of the treatment group were not significantly different from those of the placebo group. Taking Kaempferia parviflora supplements for 12 weeks may significantly enhance some physical fitness components in soccer players.

    Background and objectives BK virus reactivation in kidney transplant recipients can lead to progressive allograft injury. Reduction of immunosuppression remains the cornerstone of treatment for active BK infection. Fluoroquinolone antibiotics are known to have in vitro antiviral properties, but the evidence for their use in patients with BK viremia is inconclusive. The objective of the study was to determine the efficacy of levofloxacin in the treatment of BK viremia. Design, setting, participants, & measurements Enrollment in this prospective, multicenter, double-blinded, placebo-controlled trial occurred from July 2009 to March 2012. Thirty-nine kidney transplant recipients with BK viremia were randomly assigned to receive levofloxacin, 500 mg daily, or placebo for 30 days. Immunosuppression in all patients was adjusted on the basis of standard clinical practices at each institution. Plasma BK viral load and serum creatinine were measured monthly for 3 months and at 6 months. Results At the 3-month follow-up, the percentage reductions in BK viral load were 70.3% and 69.1% in the levofloxacin group and the placebo group, respectively (P=0.93). The percentage reductions in BK viral load were also equivalent at 1 month (58% versus and 67.1%; P=0.47) and 6 months (82.1% versus 90.5%; P=0.38). Linear regression analysis of serum creatinine versus time showed no difference in allograft function between the two study groups during the follow-up period. Conclusions A 30-day course of levofloxacin does not significantly improve BK viral load reduction or allograft function when used in addition to overall reduction of immunosuppression.

    with a positive histamine release test to Penicillium chrysogenum were exposed double- blinded to either placebo, approximately 600,000 spores/m3 air of P. chrysogenum or approximately 350,000 spores/m3 of Trichoderma harzianum for 6 min on three separate days. A statistically significant rise in symptoms from...... mucous membranes appeared from the 9-graded symptom scale after exposure to T. harzianum or placebo. Dichotomizing the data, whether the participants experienced at least a two-step rise on the symptom scale or not, gave borderline increase in mucous membrane symptoms after exposure to P. chrysogenum...... to placebo in eight sensitive school employees. However, a statistical type II error cannot be excluded because of the small sample size. PRACTICAL IMPLICATIONS: In this double blind, placebo controlled study of mold exposure changes in symptoms, objective measurements and blood samples were small and mostly...

    Full Text Available Abstract Background Colorectal cancer (CRC is one of the most commonly occurring neoplasms and a leading cause of cancer death worldwide, and new preventive strategies are needed to lower the burden of this disease. Eicosapentaenoic acid (EPA, the omega-3 polyunsaturated fatty acid that is widely used in the treatment of hyperlipidemia and prevention of cardiovascular disease, has recently been suggested to have a suppressive effect on tumorigenesis and cancer cell growth. In CRC chemoprevention trials, in general, the incidence of polyps or of the cancer itself is set as the study endpoint. Although the incidence rate of CRC would be the most reliable endpoint, use of this endpoint would be unsuitable for chemoprevention trials, because of the relatively low occurrence rate of CRC in the general population and the long-term observation period that it would necessitate. Moreover, there is an ethical problem in conducting long-term trials to determine whether a test drug might be effective or harmful. Aberrant crypt foci (ACF, defined as lesions containing crypts that are larger in diameter and stain more darkly with methylene blue than normal crypts, are considered as a reliable surrogate biomarker of CRC. Thus, we devised a prospective randomized controlled trial as a preliminary study prior to a CRC chemoprevention trial to evaluate the chemopreventive effect of EPA against colorectal ACF formation and the safety of this drug, in patients scheduled for polypectomy. Methods This study is a multicenter, double-blind, placebo-controlled, randomized controlled trial to be conducted in patients with both colorectal ACF and colorectal polyps scheduled for polypectomy. Eligible patients shall be recruited for the study and the number of ACF in the rectum counted at the baseline colonoscopy. Then, the participants shall be allocated randomly to either one of two groups, the EPA group and the placebo group. Patients in the EPA group shall receive oral

    Background Remote ischemic preconditioning (RIPC) has been shown to enhance the tolerance of remote organs to cope with a subsequent ischemic event. We hypothesized that RIPC reduces postoperative neurocognitive dysfunction (POCD) in patients undergoing complex cardiac surgery. Methods We conducted a prospective, randomized, double-blind, controlled trial including 180 adult patients undergoing elective cardiac surgery with cardiopulmonary bypass. Patients were randomized either to RIPC or to control group. Primary endpoint was postoperative neurocognitive dysfunction 5–7 days after surgery assessed by a comprehensive test battery. Cognitive change was assumed if the preoperative to postoperative difference in 2 or more tasks assessing different cognitive domains exceeded more than one SD (1 SD criterion) or if the combined Z score was 1.96 or greater (Z score criterion). Results According to 1 SD criterion, 52% of control and 46% of RIPC patients had cognitive deterioration 5–7 days after surgery (p = 0.753). The summarized Z score showed a trend to more cognitive decline in the control group (2.16±5.30) compared to the RIPC group (1.14±4.02; p = 0.228). Three months after surgery, incidence and severity of neurocognitive dysfunction did not differ between control and RIPC. RIPC tended to decrease postoperative troponin T release at both 12 hours [0.60 (0.19–1.94) µg/L vs. 0.48 (0.07–1.84) µg/L] and 24 hours after surgery [0.36 (0.14–1.89) µg/L vs. 0.26 (0.07–0.90) µg/L]. Conclusions We failed to demonstrate efficacy of a RIPC protocol with respect to incidence and severity of POCD and secondary outcome variables in patients undergoing a wide range of cardiac surgery. Therefore, definitive large-scale multicenter trials are needed. Trial Registration ClinicalTrials.gov NCT00877305 PMID:23741380

    Full Text Available AbstractBackground and purpose: Symptoms of chronic rhinisinositis (CRS are cumbersome and refractory to most systemic medications and even after surgical intervention, the recurrence of symptoms are frequent. In order to study the beneficial effects of Origanum vulgar inhaler in relaxing the symptoms, this study was conducted in Boo Ali Sina Hospital, Sari, Iran.Materials and Methods: The study was a randomized double blind placebo controlled clinical trial carried out from April to December 2005. The diagnosis of CRS was made by an ENT specialist upon clinical and CT scan findings and or signs during functional endoscopy sinuses surgery (FESS. Patients younger than 15 years old, with a history of allergic eye disease and symptoms of infections were excluded. Patients were randomized in case and control groups (32 in each according to age, sex and disease chronicity. After verbal explanation of the trial, an informed consent form was signed by each patient. The study was approved by the medical ethics committee of the Mazandaran University of Medical Sciences, Iran. Origanum vulgar was gathered from local mountains (Kojor area, Nour, Mazandaran, Iran, and identified by an experienced botanist. The airial organs of the herb were dried, macerated followed by 75% hydroalcoholic extraction and standardized by Emerson method. The active ingredient and placebo in the same bottles were administered to the patients and they were asked to add 5 ml of the liquid to boiling water and inhale it for 15 minutes, three times a day for two weeks. A telephone contact was made to the patients, to increase the compliance to treatment. A questionnaire was filled in for each patient before and after the intervention by a doctor blind to groups. Chi square test was used for comparing the differences in symptoms and P< 0.05 was considered statistically significant.Results: Sixty four patients were recruited and allocated equally in case and control groups matched for

    Taurine is an inhibitory neuromodulatory amino acid in the central nervous system that activates the GABA- and glycine-insensitive chloride channel and inhibits the N-methyl-D-aspartate receptor. It also functions as a neuroprotective agent and has a role in neural development and neurogenesis. The aim of this study was to determine the efficacy of adjunctive taurine in improving symptomatology and cognition among patients with a DSM-IV first-episode psychotic disorder. 121 patients with first-episode psychosis, aged 18-25 years, attending early intervention services consented to participate in this randomized, double-blind, placebo-controlled trial conducted from January 2007 to May 2009. Patients taking low-dose antipsychotic medication were randomly assigned to receive once-daily taurine 4 g or placebo for 12 weeks. The coprimary outcomes were change in symptomatology (measured by the Brief Psychiatric Rating Scale [BPRS] total score) and change in cognition (measured by the Measurement and Treatment Research to Improve Cognition in Schizophrenia [MATRICS] Consensus Cognitive Battery composite score) at 12 weeks. Secondary outcomes included tolerability and safety and additional clinical and functioning measures. 86 participants (n = 47 taurine; n = 39 placebo) were included in the final analysis. Taurine significantly improved symptomatology measured by the BPRS total score (95% CI, 1.8-8.5; P = .004) and psychotic subscale (95% CI, 0.1-1.5; P = .026) compared to placebo. Additionally, improvements were observed in the Calgary Depression Scale for Schizophrenia (95% CI, 0.1-3.0; P = .047) and Global Assessment of Functioning (95% CI, 0.3-8.8; P = .04) scores. There was no group difference in composite cognitive score (95% CI, -1.7 to 1.0; P = .582). A significant group difference was found on one safety and tolerability item (psychic item 2, asthenia/lassitude/increased fatigability) of the Udvalg for Kliniske Undersogelser, with the taurine group showing a

    Objective To evaluate the efficacy and safety of oseltamivir phosphate as treatment for naturally acquired influenza infection. Methods This study was conducted as a double-blind, randomized, placebo-controlled, multicenter trial during the influenza epidemic season from January to April 2001 at 7 centers in China. A total of 478 adults without other medical history, aged 18 to 65 years, were enrolled into the study. All subjects demonstrated febrile respiratory illness of no more than 36 hours' duration with a temperature of 37.8℃ or more plus at least two of the following symptoms: coryza/nasal congestion, sore throat, cough, myalgia/muscles aches and pain, fatigue, headache or chills/sweats. Individuals were randomized into either the oseltamivir phosphate or placebo group with identical-looking capsules. Either oral oseltamivir phosphate, 75 mg twice daily, or placebo was administered to the subjects for 5 days.Results A total of 451 individuals were analyzed for efficacy as the intent-to-treat population (ITT) (216 oseltamivir and 235 placebo) and 273 individuals were identified as influenza-infected through laboratory test, who were then defined as the intent-to-treat infected population (ITTI) (134 oseltamivir and 139 placebo). Four hundred and fifty nine individuals were included in the safety analysis. In the ITTI population, the cumulative alleviation proportion of oseltamivir group was significantly higher than that of the placebo group (P=0.0466)). The median duration of illness was 91.6 h [95% confidence interval (CI)=80.2-101.3 h] in the oseltamivir group and 95 h (95% CI=84.5-105.3 h) in the placebo group. The median area under the curve of decreased total score was significantly higher in the oseltamivir group than in the placebo group, 1382.9 and 1236.7 score-hours, respectively (P=0.0196). For the ITT population, similar results were observed. Adverse events (AE) were similarly reported in both the oseltamivir group and the placebo group. The

    Full Text Available BACKGROUND: Pulmonary cachexia is common in advanced chronic obstructive pulmonary disease (COPD, culminating in exercise intolerance and a poor prognosis. Ghrelin is a novel growth hormone (GH-releasing peptide with GH-independent effects. The efficacy and safety of adding ghrelin to pulmonary rehabilitation (PR in cachectic COPD patients were investigated. METHODOLOGY/PRINCIPAL FINDINGS: In a multicenter, randomized, double-blind, placebo-controlled trial, 33 cachectic COPD patients were randomly assigned PR with intravenous ghrelin (2 µg/kg or placebo twice daily for 3 weeks in hospital. The primary outcomes were changes in 6-min walk distance (6-MWD and the St. George Respiratory Questionnaire (SGRQ score. Secondary outcomes included changes in the Medical Research Council (MRC scale, and respiratory muscle strength. At pre-treatment, serum GH levels were increased from baseline levels by a single dose of ghrelin (mean change, +46.5 ng/ml; between-group p<0.0001, the effect of which continued during the 3-week treatment. In the ghrelin group, the mean change from pre-treatment in 6-MWD was improved at Week 3 (+40 m, within-group p = 0.033 and was maintained at Week 7 (+47 m, within-group p = 0.017, although the difference between ghrelin and placebo was not significant. At Week 7, the mean changes in SGRQ symptoms (between-group p = 0.026, in MRC (between-group p = 0.030, and in maximal expiratory pressure (MEP; between-group p = 0.015 were better in the ghrelin group than in the placebo group. Additionally, repeated-measures analysis of variance (ANOVA indicated significant time course effects of ghrelin versus placebo in SGRQ symptoms (p = 0.049 and MEP (p = 0.021. Ghrelin treatment was well tolerated. CONCLUSIONS/SIGNIFICANCE: In cachectic COPD patients, with the safety profile, ghrelin administration provided improvements in symptoms and respiratory strength, despite the lack of a significant between

    The consumption of dietary antioxidants is considered to be a good strategy against photo-aging. However, the results of previous clinical trials that investigated the effects of oral consumption of high-flavanol cocoa products on skin photo-aging have been contradictory. The aim of this study was to investigate whether high-flavanol cocoa supplementation would improve the moderately photo-aged facial skin of female participants, by assessing skin wrinkles and elasticity. We performed a 24-wk, randomized, double-blind, placebo-controlled study to evaluate the effects of oral supplementation of cocoa flavanols on cutaneous photo-aging. All participants were moderately photo-aged Korean women with visible facial wrinkles (age range: 43-86 y). Participants were randomly assigned to receive a placebo beverage or cocoa beverage that contained 320 mg total cocoa flavanols/d. We measured wrinkles, skin elasticity, and hydration at baseline and at 12 and 24 wk. The primary endpoint was the mean percentage change in the average roughness value (Rz) at 24 wk. At 24 wk, the mean percentage change in Rz (primary endpoint) was significantly lower in the cocoa group than in the placebo group (-8.7 percentage points; 95% CI: -16.1, -1.3 percentage points; P = 0.023). The mean percentage changes in gross elasticity, as determined by a cutometer, also differed between the groups at 12 wk (9.1 percentage points; 95% CI: 1.5, 16.7 percentage points; P = 0.020) and 24 wk (8.6 percentage points; 95% CI: 1.0, 16.2 percentage points; P = 0.027). However, there were no significant differences in skin hydration and barrier integrity between the 2 groups. In moderately photo-aged women, regular cocoa flavanol consumption had positive effects on facial wrinkles and elasticity. Cocoa flavanol supplementation may contribute to the prevention of the progression of photo-aging.

    Full Text Available Abstract Background High antibiotic resistance is described in atypical Mycobacteriosis, mainly by Mycobacterium avium complex (MAC. Methods A randomized, double-blind, placebo-controlled clinical trial was carried out in two hospitals to evaluate the effect of interferon (IFN gamma as immunoadjuvant to chemotherapy on patients with atypical mycobacteria lung disease. Patients received placebo or 1 × 106 IU recombinant human IFN gamma intramuscularly, daily for one month and then three times per week up to 6 months as adjuvant to daily oral azithromycin, ciprofloxacin, ethambutol and rifampin. Sputum samples collection for direct smear observation and culture as well as clinical and thorax radiography assessments were done during treatment and one year after. Cytokines and oxidative stress determinations were carried out in peripheral blood before and after treatment. Results Eighteen patients were included in the IFN group and 14 received placebo. Groups were homogeneous at entry; average age was 60 years, 75% men, 84% white; MAC infection prevailed (94%. At the end of treatment, 72% of patients treated with IFN gamma were evaluated as complete responders, but only 36% in the placebo group. The difference was maintained during follow-up. A more rapid complete response was obtained in the IFN group (5 months before, with a significantly earlier improvement in respiratory symptoms and pulmonary lesions reduction. Disease-related deaths were 35.7% of the patients in the placebo group and only 11.1% in the IFN group. Three patients in the IFN group normalized their globular sedimentation rate values. Although differences in bacteriology were not significant during the treatment period, some patients in the placebo group converted again to positive during follow-up. Significant increments in serum TGF-beta and advanced oxidation protein products were observed in the placebo group but not among IFN receiving patients. Treatments were well tolerated

    Full Text Available Atypical antipsychotics exhibit metabolic side effects including diabetes mellitus and obesity. The adverse events are preceded by acute worsening of oral glucose tolerance (oGTT along with reduced plasma free fatty acids (FFA and leptin in animal models. It is unclear whether the same acute effects occur in humans.A double blind, randomized, placebo-controlled crossover trial was conducted to examine the potential metabolic effects of olanzapine in healthy volunteers. Participants included male (8 and female (7 subjects [18-30 years old, BMI 18.5-25]. Subjects received placebo or olanzapine (10 mg/day for three days prior to oGTT testing. Primary endpoints included measurement of plasma leptin, oral glucose tolerance, and plasma free fatty acids (FFA. Secondary metabolic endpoints included: triglycerides, total cholesterol, high- and low-density lipoprotein cholesterol, heart rate, blood pressure, body weight and BMI. Olanzapine increased glucose Area Under the Curve (AUC by 42% (2808±474 vs. 3984±444 mg/dl·min; P = 0.0105 during an oGTT. Fasting plasma leptin and triglycerides were elevated 24% (Leptin: 6.8±1.3 vs. 8.4±1.7 ng/ml; P = 0.0203 and 22% (Triglycerides: 88.9±10.1 vs. 108.2±11.6 mg/dl; P = 0.0170, whereas FFA and HDL declined by 32% (FFA: 0.38±0.06 vs. 0.26±0.04 mM; P = 0.0166 and 11% (54.2±4.7 vs. 48.9±4.3 mg/dl; P = 0.0184, respectively after olanzapine. Other measures were unchanged.Olanzapine exerts some but not all of the early endocrine/metabolic changes observed in rodent models of the metabolic side effects, and this suggest that antipsychotic effects are not limited to perturbations in glucose metabolism alone. Future prospective clinical studies should focus on identifying which reliable metabolic alterations might be useful as potential screening tools in assessing patient susceptibility to weight gain and diabetes caused by atypical antipsychotics.ClinicalTrials.gov NCT00741026.

    2011-02-01

    Full Text Available Abstract Background Homeopathy is often sought by patients with depression. In classical homeopathy, the treatment consists of two main elements: the case history and the prescription of an individually selected homeopathic remedy. Previous data suggest that individualized homeopathic Q-potencies were not inferior to the antidepressant fluoxetine in a sample of patients with moderate to severe depression. However, the question remains whether individualized homeopathic Q-potencies and/or the type of the homeopathic case history have a specific therapeutical effect in acute depression as this has not yet been investigated. The study aims to assess the two components of individualized homeopathic treatment for acute depression, i.e., to investigate the specific effect of individualized Q-potencies versus placebo and to investigate the effect of different approaches to the homeopathic case history. Methods/Design A randomized, partially double-blind, placebo-controlled, four-armed trial using a 2 × 2 factorial design with a six-week study duration per patient will be performed. 228 patients diagnosed with major depression (moderate episode by a psychiatrist will be included. The primary endpoint is the total score on the 17-item Hamilton Depression Rating Scale after six weeks. Secondary end points are: Hamilton Depression Rating Scale total score after two and four weeks; response and remission rates, Beck Depression inventory total score, quality of life and safety at two, four and six weeks. Statistical analyses will be by intention-to-treat. The main endpoint will be analysed by a two-factorial analysis of covariance. Within this model generalized estimation equations will be used to estimate differences between verum and placebo, and between both types of case history. Discussion For the first time this study evaluates both the specific effect of homeopathic medicines and of a homeopathic case taking in patients with depression. It is an

    Full Text Available BACKGROUND: Blockade of the renin-angiotensin system (RAS reduces the incidence of type 2 diabetes mellitus. In rodents, it has been demonstrated that RAS blockade improved adipose tissue (AT function and glucose homeostasis. However, the effects of long-term RAS blockade on AT function have not been investigated in humans. Therefore, we examined whether 26-wks treatment with the angiotensin II type 1 receptor blocker valsartan affects AT function in humans with impaired glucose metabolism (IGM. METHODOLOGY/PRINCIPAL FINDINGS: We performed a randomized, double-blind, placebo-controlled parallel-group study, in which 38 subjects with IGM were treated with valsartan (VAL, 320 mg/d or placebo (PLB for 26 weeks. Before and after treatment, an abdominal subcutaneous AT biopsy was collected for measurement of adipocyte size and AT gene/protein expression of angiogenesis/capillarization, adipogenesis, lipolytic and inflammatory cell markers. Furthermore, we evaluated fasting and postprandial AT blood flow (ATBF ((133Xe wash-out, systemic inflammation and insulin sensitivity (hyperinsulinemic-euglycemic clamp. VAL treatment markedly reduced adipocyte size (P<0.001, with a shift toward a higher proportion of small adipocytes. In addition, fasting (P = 0.043 and postprandial ATBF (P = 0.049 were increased, whereas gene expression of angiogenesis/capillarization, adipogenesis and macrophage infiltration markers in AT was significantly decreased after VAL compared with PLB treatment. Interestingly, the change in adipocyte size was associated with alterations in insulin sensitivity and reduced AT gene expression of macrophage infiltration markers. VAL did not alter plasma monocyte-chemoattractant protein (MCP-1, TNF-α, adiponectin and leptin concentrations. CONCLUSIONS/SIGNIFICANCE: 26-wks VAL treatment markedly reduced abdominal subcutaneous adipocyte size and AT macrophage infiltration markers, and increased ATBF in IGM subjects. The VAL

    Which is better, Tramadol or Celecoxib, in reducing pain associated with outpatient hysteroscopy? Both Tramadol and Celecoxib are effective in reducing pain associated with outpatient hysteroscopy but Celecoxib may be better tolerated. Pain is the most common cause of failure of outpatient hysteroscopy. A systematic review and meta-analysis showed that local anaesthetics were effective in reducing pain associated with hysteroscopy but there was insufficient evidence to support the use of oral analgesics, opioids and non-steroidal anti-inflammatory drugs, to reduce hysteroscopy-associated pain and further studies were recommended. This was a randomized double-blind placebo-controlled trial with balanced randomization (allocation ratio 1:1:1) conducted in a university hospital from May 2014 to November 2014. Two hundred and ten women who had diagnostic outpatient hysteroscopy were randomly divided into three equal groups: Group 1 received oral Tramadol 100 mg, group 2 received Celecoxib 200 mg and group 3 received an oral placebo. All the drugs were given 1 h before the procedure. A patient's perception of pain was assessed during the procedure, immediately afterwards and 30 min after the procedure with the use of a visual analogue scale (VAS). There was a significant difference in the pain scores among the groups during the procedure, immediately afterwards and 30 min after the procedure (PTramadol had significantly lower pain scores when compared with the placebo during the procedure (mean difference = 1.54, 95% confidence interval (CI) (0.86, 2.22), P Tramadol and Celecoxib at any time. Time until no pain differed significantly among the groups (P = 0.01); it was shorter with both Tramadol and Celecoxib groups when compared with placebo (P = 0.002 and 0.046, respectively). The procedure failed to be completed in one patient in the placebo group but no failure to complete the procedure occurred in Tramadol and Celecoxib groups. Four women in the Tramadol group

    Objective To evaluate the efficacy and safety of defibrase in patients with acute cerebral infarction by a large sample,multicenter, randomized, double-blind, placebo-controlled clinical trial.Methods Patients with acute cerebral infarction within 12 hours of stroke onset were randomly assigned to receive either an initial intravenous infusion of defibrase 15 U plus normal saline 250 Ml or 250 Ml of normal saline only.Subsequent infusions of defibrase 15 U or placebo (normal saline) were given on the 3rd, 5th, 7th, and 9th day, respectively.Both groups received standard care of acute cerebral infarction. The primary efficacy outcome was functional status(Barthel Index) at 3 months after treatment. Safety outcome were bleeding events and mortality rate. Secondary outcome included Chinese Stroke Scale (CSS) score at 14 days and recurrence rate of stroke at 1 year. Results A total of 1053 patients were enrolled at 46 centers from September 2001 to July 2003, and 527 patients were randomly assigned to receive defibrase and 526 to receive placebo. A similar proportion of patients in both groups completed a full course of treatment. There was a significantly greater proportion of favorable functional status (Barthel Index ≥95) in defibrase group than in placebo group at 3 months (52.2% vs. 42.8%, P < 0.01), and the proportion of dependent functional status (Barthel Index ≤60) was a little lower in defibrase group compared with placebo group(27.7%vs. 32.4%). These differences were more obvious among patients who were treated within 6 hours of stroke onset.Patients in defibrase group had better improvement with respect to CSS score than those in placebo group at 14 days (P <0.05). Recurrence rate of stroke at 1 year was lower in the defibrase group compared with placebo group (6.2% vs. 10.1%,P = 0.053). Patients in defibrase group had higher risk of extracranial bleeding events (4.7%vs. 1.5%, P< 0.01) and a tendency of higher risk of symptomatic intracranial hemorrhage

    Patients with sleep apnea often present with cardiac diseases and breathing difficulties, with a high risk of postoperative respiratory depression. We conducted a randomized, double-blind, prospective study in 30 adult patients with obstructive sleep apnea, undergoing elective ear-nose-throat surgery. The patients were randomly assigned to receive placebo or clonidine (2 microg/kg oral) the night before and the next morning 2 h before surgery. Spo2, heart rate, mean arterial blood pressure, snoring, and oronasal airflow were monitored for 36 h. A standard anesthesia was used consisting of propofol and remifentanil. Anesthetic drug consumption, postoperative analgesics, and pain score were recorded. In the clonidine group, mean arterial blood pressures were significantly lower during induction, operation, and emergence from anesthesia. Both propofol dose required for induction (190 +/- 32.2 mg) and anesthesia (6.3 +/- 1.3 mg . kg(-1).h(-1)) during surgery were significantly reduced in the clonidine group compared with the placebo group (induction 218 +/- 32.4, anesthesia 7.70 +/- 1.5; P clonidine group. Apnea and desaturation index were not different between the groups, whereas the minimal postoperative oxygen saturation on the day of surgery was significantly lower in the placebo than in the clonidine group (76.7% +/- 8.0% versus 82.4% +/- 5.8%; P clonidine premedication stabilizes hemodynamic variables during induction, maintenance, and emergence from anesthesia and reduces the amount of intraoperative anesthetics and postoperative opioids without deterioration of ventilation.

    Full Text Available Acute gastroenteritis is one of the most common infectious diseases of childhood. Its symptoms are vomiting, diarrhea, and dehydration. In the emergency ward, intravenous rather than oral rehydration is usually preferred because of the high likelihood of emesis. Treatments to reduce emesis are of value in improving the rehydration procedure. Our study is a double-blind randomized trial and proposes the use of ondansetron as an anti-emetic drug to treat children with acute gastroenteritis. Seventy-four in-patients, aged 3 months to 15 years, were enrolled and randomly assigned to an ondansetron or placebo group. Inclusion criteria were the diagnosis of acute gastroenteritis and the absence of other diseases or allergies to drugs. A single bolus (0.15 mg/kg of ondansetron was injected intravenously; normal 0.9% saline solution was used as a placebo. This treatment induced vomiting cessation in the ondansetron group significantly in comparison to the placebo group. The length of the hospital stay and the oral rehydration fluid volume were similar in the two groups and no adverse effects were noticed. Thus, safety, low cost, and overall bene­fit of ondansetron treatment suggests that this drug can be administered successfully to children with acute gastroenteritis.

    Full Text Available Objective. This randomized double-blind study compared the analgesic efficacy and tolerability of etoricoxib versus ketoprofen in 165 patients with elective total primary knee arthroplasty. Methods. After ethical committee approval, 165 patients were randomized in 3 groups: the etoricoxib group (E receiving etoricoxib 120 mg/day, at the end of surgery and in the first postoperative day; the ketoprofen group (K receiving ketoprofen 2 pills of 100 mg/day, the first at the end of surgery and then 1 pill every 12 hours in the surgery day and the first postoperative day; the placebo group (P. All groups received postoperatively the same analgesia protocol when NRS is over 3 with IV Perfalgan and morphine. The effectiveness was evaluated by the time from the initiation of spinal anesthesia until the first analgesic dose, the total amount of morphine administered in the surgery day and the first postoperative day, and the frequency of patients with side effects and necessary amount of adjuvant medication. Results. The baseline demographic characteristics were similar among the 3 groups. In both study days etoricoxib provided an analgesic effect superior to placebo and to ketoprofen, the total administered morphine being significantly lower in etoricoxib group. There were no statistically significant differences between groups regarding the side effects.

    To determine that perioperative ondansetron reduces the analgesic efficacy of acetaminophen. Randomized, double-blinded study. 120 patients ASA I-II who underwent abdominal hysterectomy. All the patients were given 1g acetaminophen at skin closure. Patients were divided into two groups; ondansetron HCl (8mg, 2ml IV) (Group I, N=60) and saline (2ml IV) (Group II, N=60) at the skin closure. Postoperative pain scores (VAS) while resting in bed and sitting, total opioid consumption were noted. Patients randomized to ondansetron had significantly worse pain scores upon arrival to the recovery unit [by 1.7 (99.7% CI: 0.75, 2.59) cm] and at 1h [by 1.3 (0.5, 2.1) cm] while resting in bed. Pain scores while sitting were also significantly greater in ondansetron group at arrival in PACU by 0.6 (99.7% CI: 0.1, 1.0) cm. Thereafter, pain scores did not differ significantly. Median total opioid (tramadol) consumption was 441 [Q1, Q3: 280, 578] mg in the ondansetron group and 412 [309, 574] mg in the placebo group, P=0.95. Ondansetron significantly decreased the analgesic effect of acetaminophen during the initial postoperative period. Our results thus confirm that acetaminophen analgesia is partially mediated by serotonin receptors. However, the reduction was of marginal clinical importance and short-lived.

    Background Several nonsteroidal anti-inflammatory drugs (NSAIDs) have been shown to be effective in the treatment of migraine. However, few commercially available NSAIDs can be administered IV. Lysine clonixinate (LC), an NSAID derived from nicotinic acid, has been proved effective in various algesic syndromes (eg, renal colic, muscular pain, nerve compression, odontalgia). The oral formulation of LC has been shown to be effective in the treatment of migraine of moderate severity. Objective The aim of this study was to assess the efficacy and tolerability of the IV formulation of LC in the treatment of severe migraine. Methods This double-blind, randomized, placebo-controlled, prospective study enrolled patients with severe migraine (without aura) as defined by the criteria of the International Headache Society. When patients presented to a neurology hospital with an outpatient headache unit (Instituto de Neurologia Deolindo Couto, Rio de Janeiro, Brazil) with a severe migraine attack that had lasted <4 hours, they were randomized to 1 of 2 groups (IV placebo [25 mL of 0.9% saline] or IV LC [21 mL of 0.9% saline plus 4 mL of LC 200 mg]). Headache intensity and adverse effects (AEs) were assessed before (0 minute) and 30, 60, and 90 minutes after study drug administration. Rescue medication was available 2 hours after study drug administration, and its use was compared between groups. Results Thirty-two patients (23 women, 9 men; mean [SD] age, 32 [2] years; range, 18–58 years) entered the study. Twenty-nine patients (21 women, 8 men; mean [SD] age, 32 [2] years; range, 18–56 years) completed the study. Three patients (all in the placebo group) did not complete the study (1 patient was unable to rate the pain severity after drug administration and 2 patients refused IV drug administration). Among study completers, 17 patients received LC and 12 placebo. At 30 minutes, 1 patient (8.3%) in the placebo group and 5 patients (29.4%) in the LC group were pain free

    Full Text Available Abstract Background Pneumonia is a leading cause of children's deaths in developing countries and hinders achievement of the fourth Millennium Development Goal. This goal aims to reduce the under-five mortality rate, by two thirds, between 1990 and 2015. Few studies have examined the impact of zinc adjunct therapy on the outcome of childhood pneumonia. We determined the effect of zinc as adjunct therapy on time to normalization of respiratory rate, temperature and oxygen saturation. We also studied the effect of zinc adjunct therapy on case fatality of severe childhood pneumonia (as a secondary outcome in Mulago Hospital, Uganda. Methods In this double blind, randomized, placebo-controlled clinical trial, 352 children aged 6 to 59 months, with severe pneumonia were randomized to zinc (20 mg for children ≥12 months, and 10 mg for those Results Time to normalization of the respiratory rate, temperature and oxygen saturation was not significantly different between the two arms.

    Full Text Available Abstract Background Results of preclinical studies suggest that the GABAB receptor agonist baclofen may be useful in treatment of opioid dependence. This study was aimed at assessing the possible efficacy of baclofen for maintenance treatment of opioid dependence. Methods A total of 40 opioid-dependent patients were detoxified and randomly assigned to receive baclofen (60 mg/day or placebo in a 12-week, double blind, parallel-group trial. Primary outcome measure was retention in treatment. Secondary outcome measures included opioids and alcohol use according to urinalysis and self-report ratings, intensity of opioid craving assessed with a visual analogue scale, opioid withdrawal symptoms as measured by the Short Opiate Withdrawal Scale and depression scores on the Hamilton inventory. Results Treatment retention was significantly higher in the baclofen group. Baclofen also showed a significant superiority over placebo in terms of opiate withdrawal syndrome and depressive symptoms. Non-significant, but generally favorable responses were seen in the baclofen group with other outcome measures including intensity of opioid craving and self-reported opioid and alcohol use. However, no significant difference was seen in the rates of opioid-positive urine tests. Additionally, the drug side effects of the two groups were not significantly different. Conclusion The results support further study of baclofen in the maintenance treatment of opioid dependence.

    To evaluate the efficacy and tolerability of flexible-dose fesoterodine vs placebo in subjects with overactive bladder (OAB). In a 12-week double-blind trial, subjects were randomized to fesoterodine 4 mg or placebo once daily, taken within 4 hours of bedtime. At week 2, subjects could increase the fesoterodine dose to 8 mg (sham escalation for placebo). Subjects completed 3-day bladder diaries, Patient Perception of Bladder Condition, and Urgency Perception Scale at baseline and weeks 2, 6, and 12 as well as OAB Questionnaire at baseline and week 12. Of 883 subjects, 63% and 73% of the fesoterodine (n = 438) and placebo (n = 445) groups, respectively, opted for dose escalation. Week 12 improvements from baseline in total micturitions, urgency episodes, urgency urinary incontinence episodes, frequency-urgency sum, and all OAB Questionnaire scales and domains, but not nocturnal micturitions or nocturnal urgency episodes, were significantly greater with fesoterodine than placebo (all P fesoterodine had improved Patient Perception of Bladder Condition and Urgency Perception Scale scores at weeks 2, 6, and 12 (P fesoterodine, 26%; placebo, 8%) and constipation (fesoterodine, 11%; placebo, 6%) were the most common adverse events. In both groups, 87% of the subjects completed the trial; 8% and 5% of the fesoterodine and placebo groups, respectively, discontinued because of an adverse event. Flexible-dose fesoterodine was efficacious and generally well tolerated for treatment of OAB symptoms. 2010 Elsevier Inc. All rights reserved.

    Roxatidine acetate, a new H2 receptor antagonist, was compared with ranitidine in the treatment of duodenal ulcers in a double-blind multicentre study. Eighty-four patients with endoscopically proven duodenal ulcer were randomized to receive 150 mg roxatidine acetate or 300 mg ranitidine at bedtime. Repeat endoscopy was performed after 4 weeks (25-33 days) and if the ulcer had not healed, another endoscopy was performed after a further 4 weeks of treatment. Using per protocol analysis 73.6% of ulcers treated with roxatidine healed at 4 weeks compared to 72.2% of ulcers treated with ranitidine (P = NS). The healing rates at 8 weeks were 92% with roxatidine and 83.3% with ranitidine (P = NS). Using equivalence tests, the healing rate of roxatidine was found to be equivalent to that of ranitidine within a 20% region. Roxatidine users took significantly less antacids than ranitidine users (P roxatidine or ranitidine. Roxatidine is a safe effective drug in the treatment of duodenal ulcers with a healing rate comparable to that of ranitidine.

    The purpose of this study was to evaluate, using a randomized, double-blind methodology: (1) the safety of phentolamine mesylate (Oraverse) in accelerating the recovery of soft tissue anesthesia following the injection of two percent lidocaine plus 1:100,000 epinephrine in two- to five-year-olds; and (2) efficacy in four- to five-year-olds only. One hundred fifty pediatric dental patients underwent routine dental restorative procedures with two percent lidocaine plus 1:100,000 epinephrine with doses based on body weight. Phentolamine mesylate or a sham injection (two to one ratio) was then administered. Subjects were monitored for safety and, in four- to five-year-olds, for efficacy during the two-hour evaluation period. There were no significant differences in adverse events between the phentolamine and sham injections. Compared to sham, phentolamine was not associated with nerve injury, increased analgesic use, or abnormalities of the oral cavity. Phentolamine was associated with transient decreased blood pressure in some children. In four- and five-year-olds, phentolamine induced more rapid recovery of lip anesthesia by 48 minutes (Pfive-year-olds; in four- to five-year-olds, a statistically significant more rapid recovery of lip sensation compared to sham injections was determined.

    Full Text Available Abstract Background and objectives: There are many studies conducted on reducing the frequency and severity of fentayl-induced cough during anesthesia induction. We propose that pheniramine maleate, an antihistaminic, may suppress this cough. We aim to observe the effect of pheniramine on fentanyl-induced cough during anesthesia induction. Methods: This is a double-blinded, prospective, three-arm parallel, randomized clinical trial of 120 patients with ASA (American Society of Anesthesiologists physical status III and IV who aged ≥18 and scheduled for elective open heart surgery during general anesthesia. Patients were randomly assigned to three groups of 40 patients, using computer-generated random numbers: placebo group, pheniramine group, and lidocaine group. Results: Cough incidence differed significantly between groups. In the placebo group, 37.5% of patients had cough, whereas the frequency was significantly decreased in pheniramine group (5% and lidocaine group (15% (Fischer exact test, p = 0.0007 and p = 0.0188, respectively. There was no significant change in cough incidence between pheniramine group (5% and lidocaine group (15% (Fischer exact test, p = 0.4325. Cough severity did also change between groups.

There was no significant change in cough severity between pheniramine group and lidocaine group (p = 0.856. Conclusion: Intravenous pheniramine is as effective as lidocaine in preventing fentayl-induced cough. Our results emphasize that pheniramine is a convenient drug to decrease this cough.

    No drug to treat vascular dementia (VaD) has yet been approved by the American or European authorities, leaving a large population of patients without effective therapy. Cerebrolysin has a long record of safety and might be efficacious in this condition. We conducted a large, multicenter, double-blind, placebo-controlled study in 242 patients meeting the criteria for VaD. The primary endpoint was the combined outcome of cognition (based on Alzheimer's Disease Assessment Scale Cognitive Subpart, Extended Version [ADAS-cog+] score) and overall clinical functioning (based on Clinician's Interview-Based Impression of Change plus Caregiver Input [CIBIC+] score) assessed after 24 weeks of treatment. Intravenous Cerebrolysin 20 mL was administered once daily over the course of 2 treatment cycles as add-on therapy to basic treatment with acetylsalicylic acid. The addition of Cerebrolysin was associated with significant improvement in both primary parameters. At week 24, ADAS-cog+ score improved by 10.6 points in the Cerebrolysin group, compared with 4.4 points in the placebo group (least squares mean difference, -6.17; P Cerebrolysin group (ADAS-cog+ improvement of ≥4 points from baseline, 82.1% vs 52.2%; CIBIC+ score of Cerebrolysin, the odds ratio for achieving a favorable CIBIC+ response was 5.08 (P Cerebrolysin significantly improved clinical outcome, and that the benefits persisted for at least 24 weeks. Cerebrolysin was safe and well tolerated.

    The antidepressant efficacy and safety of desvenlafaxine succinate (desvenlafaxine) were evaluated in a phase III, double-blind, placebo-controlled study. Outpatients with a primary diagnosis of major depressive disorder were treated with fixed once-daily doses of desvenlafaxine 200 or 400 mg for 8 weeks. The primary efficacy measure was change from baseline on the 17-item Hamilton Rating Scale for Depression. At the final on-therapy evaluation, adjusted mean change from baseline in 17-item Hamilton Rating Scale for Depression total score was greater for desvenlafaxine 200 and 400 mg/day vs. placebo. Both desvenlafaxine doses showed greater efficacy than placebo on the secondary efficacy measures, including the Clinical Global Impressions-Improvement scale scores, Montgomery-Asberg Depression Rating Scale scores, CGI-Severity, and 17-item Hamilton Rating Scale for Depression response rate. Desvenlafaxine 200 mg/day was also significantly better than placebo on remission, Visual Analog Scale-Pain Intensity overall scores, and some Visual Analog Scale-Pain Intensity subscale scores. Desvenlafaxine 400 mg/day was significantly better than placebo on selected Visual Analog Scale-Pain Intensity subscale scores. Most adverse events were mild or moderate in severity, and safety assessments revealed few clinically significant changes in vital signs, laboratory tests, and electrocardiogram results. These data provide support for the efficacy and safety of desvenlafaxine in the treatment of major depressive disorder.

    We evaluated the analgesic efficacy, safety and tolerability of a novel chemokine receptor 2 (CCR2) antagonist, AZD2423, in posttraumatic neuralgia. This was a double-blind, randomized, parallel-group, multicentre study. One hundred thirty-three patients with posttraumatic neuralgia were equally randomized to 28days' oral administration of 20mg AZD2423, 150mg AZD2423 or placebo. The primary efficacy variable was the change of average pain score from 5days at baseline to the last 5days of treatment, measured by a numerical rating scale (NRS, 0-10). The secondary efficacy measures included NRS worst pain score, patient global impression of change, pain interference on sleep and activity, and Neuropathic Pain Symptom Inventory (NPSI). The change of the NRS average pain score was not significantly different between treatment groups (AZD2423 20mg -1.54; AZD2423 150mg -1.53; placebo -1.44). There were trends towards larger reduction of NPSI total score and NPSI subscores for paroxysmal pain and paresthesia/dysesthesia by AZD2423 150mg compared to placebo. No other secondary efficacy variables differed between treatment groups. The frequency and type of adverse events for AZD2423 were similar to placebo. Increased plasma levels of chemokine ligand 2 and reduced mean levels of monocytes (-30% by AZD2423 150mg) suggested that the administrated doses of AZD2423 had interacted with the CCR2 target. The CCR2 antagonist AZD2423 demonstrated no efficacy on NRS average pain scores and most of the secondary pain variables. The NPSI data suggested possible effects on certain sensory components of pain. There were no major safety or tolerability concerns. Copyright © 2013 International Association for the Study of Pain.

    The purpose of this study was to elucidate the effects of a dual-coated probiotic supplement (Duolac Care) on symptoms of diarrhea-predominant irritable bowel syndrome in a randomized double-blind clinical trial. Fifty subjects with diarrhea-predominant irritable bowel syndrome were randomly assigned to either the non-coating group or the dual-coating group in order to receive two capsules per day of multi-species probiotics containing 5 billion bacteria per capsule for 4 weeks. Data from an adequate relief questionnaire were used in assessment of primary outcome. Daily records of stool frequencies and the Bristol stool scale, a weekly symptom diary using 100-mm visual analog scale, and Beck depression inventories were collected. Blood tests including blood cell counts, interleukin-10, tumor necrosis factor-alpha and inducible nitric oxide synthase, and regulatory T cells-CD4 + CD25(high) T cells, CD4 + LAP + T cells and CD25(high) + LAP + T cells-were analyzed before and after the study. The shift of gut microbiota was investigated using a quantitative real-time polymerase chain reaction assay. Responses to the adequate relief questionnaire indicated significant improvement in overall discomfort in the dual-coating group and the ratio of normal stools to hard or watery stools had a better effect from dual-coated probiotics compared to non-coated probiotics. This may be due to a shift of intestinal microbiota, as our correlation analysis showed significant negative correlation between Bifidobacterium and urgency of defecation. Our result implies that dual-coating layers of probiotic supplement can be a candidate for treatment of diarrhea-predominant irritable bowel syndrome.

    Accumulating evidence indicates that manic symptoms below the threshold for hypomania (mixed features) are common in individuals with major depressive disorder. This form of depression is often severe and is associated with an increased risk for recurrence, suicide attempts, substance abuse, and functional disability. This study evaluated the efficacy and safety of lurasidone in major depressive disorder with mixed features. Patients meeting DSM-IV-TR criteria for major depressive disorder who presented with two or three protocol-defined manic symptoms were randomly assigned to 6 weeks of double-blind treatment with either lurasidone at 20-60 mg/day (N=109) or placebo (N=100). Changes from baseline in Montgomery-Åsberg Depression Rating Scale score (MADRS; primary outcome measure) and Clinical Global Impressions severity subscale score (CGI-S; key secondary outcome measure) were evaluated using a mixed model for repeated-measures analysis. Lurasidone significantly improved depressive symptoms and overall illness severity, assessed by least squares mean change at week 6 in the MADRS and CGI-S scores: -20.5 compared with -13.0 (effect size, 0.80) and -1.8 compared with -1.2 (effect size, 0.60), respectively. Significant improvement in manic symptoms, assessed by the Young Mania Rating Scale, was also observed, in addition to other secondary efficacy endpoints. Rates of discontinuation due to adverse events were low. The most common adverse events were nausea (6.4% and 2.0% in the lurasidone and placebo groups, respectively) and somnolence (5.5% and 1.0%). Lurasidone was effective and well tolerated in this study involving patients with major depressive disorder associated with subthreshold hypomanic symptoms (mixed features).

    Full Text Available Abstract Background There is evidence that dyslipidemia is associated with chronic kidney disease (CKD. Experimental studies have established that lipids are damaging to the kidney and animal intervention studies show statins attenuate this damage. Small clinical trials, meta-analyses, observational studies and post-hoc analyses of cardiovascular intervention studies all support the concept that statins can reduce kidney damage in humans. Based on this background, a double blind randomized placebo controlled trial was designed to assess the effectiveness of atorvastatin 10 mg on slowing the progression of kidney disease in a population of patients with CKD. Method/Design The Lipid lowering and Onset of Renal Disease (LORD trial is a three-year, single center, multi-site, double blind, randomized, placebo controlled trial. The primary outcome measure is kidney function measured by eGFR calculated by both Modification of Diet in Renal Disease (MDRD and Cockcroft and Gault equations. Secondary outcome measures include kidney function measured by 24-hour urine creatinine clearance and also 24-hour urinary protein excretion, markers of oxidative stress, inflammation and drug safety and tolerability. Discussion The results of this study will help determine the effectiveness and safety of atorvastatin and establish its effects on oxidative stress and inflammation in patients with CKD.

    Negative symptoms and cognitive deficits are considered core symptoms of schizophrenia, yet treatment for them remains inadequate. Deep-transcranial magnetic stimulation (TMS) is a novel technology that enables non-invasive stimulation of deep layers of the prefrontal cortex. Preliminary evidence suggests that deep-TMS could be effective in the treatment of negative symptoms and cognitive deficits. The current study is the first double-blind, randomized sham-controlled study to examine the feasibility of deep-TMS add-on treatment for negative symptoms and cognitive deficits in schizophrenia. Twenty daily H1 deep-TMS treatments (20Hz, 120% MT) were delivered, in a double-blind, randomized sham-controlled design (n=30). Extensive clinical and cognitive assessments were carried out throughout the study and for an additional one month follow-up period. The results indicate that at the end of the treatment period, negative symptoms (as indicated by the Scale for the Assessment of Negative Symptoms (SANS)) significantly reduced in the TMS group (-7.7), but not in the sham group (-1.9). Differences between the groups were not statistically significant.

    The widely observed between-subject variability in cognitive responses to coffee may have a genetic basis. We evaluated cognitive responses to caffeine throughout three complex cognitive tasks assessing different subdomains of attention, namely Alerting and Orienting (Categorical Search Task) and Executive Control (Stroop Task and Eriksen Flanker Task). We explored whether they are influenced by gene variants affecting adenosine metabolism or catecholamine receptors. We recruited 106 healthy male subjects who were administered, in a double-blind design, 40mL of either a decaffeinated coffee preparation plus 3mg/kg caffeine (caf) or the corresponding vehicle (decaf). The protocol was repeated 24h later with the alternative preparation. Cognitive tasks were performed between 30min and 2h after caf or decaf administration. Each subject underwent ambulatory blood pressure monitoring for 2h. Blood samples were collected for genetic evaluations and for plasma caffeine and catecholamines measures. We found a significant reduction of reaction times in two of the cognitive tasks (Categorical Search Task and Stroop Task) after caf compared with decaf, indicating that caffeine, on average, improved the attention level in the domains under investigation. We also found, however, a great inter-individual variability in the cognitive performance responses to caffeine. In exploring genetic sources for such variability, we found a relation between polymorphisms of adenosine A2A and the caffeine effects on the attentional domains of Orienting and Executive control. In conclusion, variability in the attentional response to coffee may be partly explained by genetic polymorphisms of adenosine and adrenergic receptors.

    Full Text Available Exposure to a specific pulsed electromagnetic field (PEMF has been shown to produce analgesic (antinociceptive effects in many organisms. In a randomized, double-blind, sham-controlled clinical trial, patients with either chronic generalized pain from fibromyalgia (FM or chronic localized musculoskeletal or inflammatory pain were exposed to a PEMF (400 μT through a portable device fitted to their head during twice-daily 40 min treatments over seven days. The effect of this PEMF on pain reduction was recorded using a visual analogue scale. A differential effect of PEMF over sham treatment was noticed in patients with FM, which approached statistical significance (P=0.06 despite low numbers (n=17; this effect was not evident in those without FM (P=0.93; n=15. PEMF may be a novel, safe and effective therapeutic tool for use in at least certain subsets of patients with chronic, nonmalignant pain. Clearly, however, a larger randomized, double-blind clinical trial with just FM patients is warranted.

    AIM: To evaluate the efficacy and safety of capsule oxymatrine in the treatment of chronic hepatitis B.METHODS: A randomised double-blind and placebocontrolled multicenter trial was conducted. Injection of oxymatrine was used as positive-control drug. A total of 216 patients with chronic hepatitis B entered the study for 24 weeks, of them 108 received capsule oxymatrine, 36 received injection of oxymatrine, and 72 received placebo.After and before the treatment, clinical symptoms, liver function, serum hepatitis B virus markers, and adverse drug reaction were observed.RESULTS: Among the 216 patients, six were dropped off,and 11 inconsistent with the standard were excluded.Therefore, the efficacy and safety of oxymatrine in patients were analysed. In the capsule treated patients, 76.47 % became normal in ALT level, 38.61% and 31.91% became negative both in HBV DNA and in HBeAg. In the injection treated patients, 83.33 % became normal in ALT level,43.33 % and 39.29 % became negative both in HBV DNA and in HBeAg. In the placebo treated patients, 40.00 % became normal in ALT level, 7.46 % and 6.45 % became negative both in HBV DNA and in HBeAg. The rates of complete response and partial response were 24.51% and 57.84 % in the capsule treated patients, and 33.33 % and 50.00 % in the injection treated patients, and 2.99 % and 41.79 % in the placebo treated patients, respectively.There was no significance between the two groups of patients, but both were significantly higher than the placebo. The adverse drug reaction rates of the capsule,injection and placebo were 7.77 %, 6.67 % and 8.82 %,respectively. There was no statistically significant difference among them.CONCLUSION: Oxymatrine is an effective and safe agent for the treatment of chronic hepatitis B.

    To assess the efficacy, safety, tolerability, and pharmacokinetics of adjunctive rufinamide in adults and adolescents with inadequately controlled partial seizures receiving treatment with one to three concomitant antiepileptic drugs (AEDs). A 24-week multicenter Phase II clinical study was conducted (n=647), comprising a 12-week prospective baseline phase and a 12-week randomized double-blind, parallel-group, five-arm (placebo and rufinamide 200, 400, 800, and 1600mg/day) treatment phase. The linear trend of dose response for seizure frequency per 28 days in the double-blind treatment phase - the primary efficacy outcome measure - was statistically significant in favor of rufinamide (estimated slope=-0.049, P=0.003; minimally efficacious dose, 400mg/day). Response rates, defined as a >or=50% reduction in seizure frequency per 28 days, also revealed a significant linear trend of dose response (P=0.0019, logistic regression analysis). Adverse events were comparable between placebo and all rufinamide groups except the 1600mg/day group; no safety signals were observed. These results suggest that in the dose range of 400-1600mg/day, add-on rufinamide therapy may benefit patients with inadequately controlled partial seizures and is generally well tolerated. These data also suggest that higher doses may confer additional efficacy without adversely affecting safety and tolerability.

    Erectile dysfunction is a man's persistent or recurrent inability to achieve and maintain erection for a satisfactory sexual relationship. As diabetes is a major risk factor for erectile dysfunction, the prevalence of erectile dysfunction among diabetic men has been reported as 35% to 90%. This randomized, parallel-group, double-blind, placebo-controlled trial investigated the effects of a topical saffron (Crocus sativus L) gel on erectile dysfunction in diabetic men. Patients were randomly allocated to 2 equal groups (with 25 patients each). The intervention group was treated with topical saffron, and the control received a similar treatment with placebo. The 2 groups were assessed using the International Index of Erectile Function Questionnaire before the intervention and 1 month after the intervention. Compared to placebo, the prepared saffron gel could significantly improve erectile dysfunction in diabetic patients (P saffron can be considered as a treatment option for diabetic men with erectile dysfunction.

    AIM:To evaluated the role of hyoscine butyl bromide in facilitating retrograde ileoscopy.METHODS:Retrograde terminal ileoscopy was attempted in 200 consecutive patients undergoing colonoscopy. After intubation of the cecum and visualization of the ileocecal valve,butyl bromide injection or normal saline was given intravenously to the patients in a double blind random fashion. The pulse rate and oxygen saturation were measured continuously. After completion of the procedure,endoscopists were then asked to score the ease of intubation and the ease of visualization of the terminal ileum on a visual scale of 1 to 10. The patients were also asked to score the pain after receiving hyoscine butyl bromide injection on a score of 1 to 10.RESULTS:Terminal ileoscopy could be performed in 188 patients. The mean (SD) visual analogue score for the ease of intubation of the cecum was 7.4 (0.65) in the injection group and 5.9 (0.8) in the placebo group (P<0.001). The mean (SD) length of ileum visualized in the injection group was 14.4 (3.3) cm and 10.4 (2.7) cm in the placebo group (P<0.001). The mean (SD) visual analogue score for ease of visualization of the terminal ileum was 7.5 (0.69) in the injection group and 5.9 (0.7) in the placebo group (P<0.001). The pain score experienced by the patients was 6.5 (0.7) in the injection group and 6.7 (0.69) in the placebo group (P<0.008). Although the pulse rate increased significantly in patients receiving the drug,no statistically significant difference was noted in the oxygen saturation between the two groups either before or after administration of the drug. No complications were observed in either of the groups.CONCLUSION:Hyoscine butyl bromide injection is a useful adjunct in helping the intubation and visualizationof terminal ileum during colonoscopy.

    Full Text Available Background: The positive effects of caffeine supplementation on strength-power and endurance performance in healthy athletes have been demonstrated in many studies. A possible mechanism for its ergogenic effect relates to its influence on the central nervous system. Post-traumatic complications in cervical spinal cord injury affect almost all body systems including the nervous system. For this reason, we expect that caffeine will have a different effect of performance in the group of athletes with spinal cord injuries. Objective: To examine the effects of caffeine supplementation on maximal aerobic power in elite wheelchair rugby players. Methods: Seven elite male wheelchair rugby players with complete cervical-level SCI (C4-Th1 were recruited (mean age: 28 ± 5.42 years; mean body mass index: 26 ± 2.84 kg/m2. The effect of caffeine was assessed by an incremental arm ergometer test until volitional exhaustion. The maximal oxygen uptake (VO2max/kg, maximum power (W max/kg, peak heart rate (HR peak, and intensity of perceived exertion (RPE were measured. Participants performed the test twice with a two-week washout period. One hour before each exercise test subjects ingested a capsule of placebo or caffeine (3 mg per kg of body weight. The tests were applied in a double-blind, randomized, repeated-measures, and cross-over design. Wheelchair rugby players were chosen because of the expected high homogeneity of participants - in terms of the type and degree of disability, gender, and age of the players. Results: The monitored parameters were not significantly influenced by caffeine intervention as compared to placebo: VO2max/kg (p = .40, W max/kg (p = .34, HR peak (p = .50 and RPE (p = .50. Conclusions: The current findings suggest that a caffeine dose of 3 mg/kg body mass does not improve oxygen uptake and maximal power in elite wheelchair rugby players.

    This pilot study was devoted to the effect of static magnetic field (SMF)-exposure on erosive gastritis. The randomized, self- and placebo-controlled, double-blind, pilot study included 16 patients of the 2nd Department of Internal Medicine, Semmelweis University diagnosed with erosive gastritis. The instrumental analysis followed a qualitative (pre-intervention) assessment of the symptoms by the patient: lower heartburn (in the ventricle), upper heartburn (in the oesophagus), epigastric pain, regurgitation, bloating and dry cough. Medical diagnosis included a double-line upper panendoscopy followed by 30 min local inhomogeneous SMF-exposure intervention at the lower sternal region over the stomach with peak-to-peak magnetic induction of 3 mT and 30 mT m(-1) gradient at the target site. A qualitative (post-intervention) assessment of the same symptoms closed the examination. Sham- or SMF-exposure was used in a double-blind manner. The authors succeeded in justifying the clinically and statistically significant beneficial effect of the SMF- over sham-exposure on the symptoms of erosive gastritis, the average effect of inhibition was 56% by p = 0.001, n = 42 + 96. This pilot study was aimed to encourage gastroenterologists to test local, inhomogeneous SMF-exposure on erosive gastritis patients, so this intervention may become an evidence-based alternative or complementary method in the clinical use especially in cases when conventional therapy options are contraindicated. © 2014 The Author(s) Published by the Royal Society.

    Full Text Available Background: Coblation tonsillectomy is a new surgical technique and demands further research to be proven as a suitable and standard method of tonsillectomy. This study compares coblation and traditional tonsillectomy techniques in view of their advantages and complications. Methods: In a prospective double-blind randomized controlled trial information on operation time, intraoperative blood loss, postoperative pain, time needed to regain the normal diet and activity and post-operative hemorrhage were gathered and compared between two groups containing 47 patients in each group. Results: We found statistically significant differences in operation time (p 0.5 was not significantly different between two groups. Conclusions: This study revealed a significantly less intraoperative or postoperative complications and morbidity in coblation tonsillectomy in comparison with traditional method. Coblation was associated with less pain and quick return to normal diet and daily activity. These findings addressed coblation tonsillectomy as an advanced method.

    Urinary tract infections (UTI) are among the most prevalent microbial diseases and their financial burden on society is substantial. The continuing increase of antibiotic resistance worldwide is alarming. Thus, well-tolerated, highly effective therapeutic alternatives are urgently needed. Although there is evidence indicating that bacteriophage therapy may be effective and safe for treating UTIs, the number of investigated patients is low and there is a lack of randomized controlled trials. This study is the first randomized, placebo-controlled, double-blind trial investigating bacteriophages in UTI treatment. Patients planned for transurethral resection of the prostate are screened for UTIs and enrolled if in urine culture eligible microorganisms ≥10(4) colony forming units/mL are found. Patients are randomized in a double-blind fashion to the 3 study treatment arms in a 1:1:1 ratio to receive either: a) bacteriophage (i.e. commercially available Pyo bacteriophage) solution, b) placebo solution, or c) antibiotic treatment according to the antibiotic sensitivity pattern. All treatments are intended for 7 days. No antibiotic prophylaxes will be given to the double-blinded treatment arms a) and b). As common practice, the Pyo bacteriophage cocktail is subjected to periodic adaptation cycles during the study. Urinalysis, urine culture, bladder and pain diary, and IPSS questionnaire will be completed prior to and at the end of treatment (i.e. after 7 days) or at withdrawal/drop out from the study. Patients with persistent UTIs will undergo antibiotic treatment according to antibiotic sensitivity pattern. Based on the high lytic activity and the potential of resistance optimization by direct adaptation of bacteriophages, and considering the continuing increase of antibiotic resistance worldwide, bacteriophage therapy is a very promising treatment option for UTIs. Thus, our randomized controlled trial investigating bacteriophages for treating UTIs will provide

    To examine the efficacy and safety of otilonium bromide (OB) in treatment-sensitive functional irritable bowel syndrome (IBS) clinical parameters. Ninety-three patients (44.8 ± 12.6 years, 69% female) with IBS symptoms complying with Rome II criteria participated in this double-blind, placebo-controlled, randomised, dose-ranging phase I/II study. Patients were administered OB 20 mg (n = 24), 40 mg (n = 23) and 80 mg (n = 23) tid or placebo (n = 23) in 4 parallel groups for 4 wk. Primary efficacy variables included abdominal discomfort, intestinal habits, number of daily evacuations and stool consistency. Secondary efficacy measures included return to regular intestinal habits and global discomfort. Safety was also assessed. Baseline clinical characteristics were similar among the 4 groups. Although individual parameters such as intensity and frequency of abdominal discomfort, bloating or pain were reduced by OB over the 4 wk, no significant differences were observed between groups. Similarly, no difference was observed between OB treatment or placebo for mucus in stool and incomplete or difficulty of evacuation. However, evacuation frequency was significantly reduced after 4 wk by 80 mg OB compared to placebo (-8.36% for placebo vs -41.9% for 80 mg OB, P < 0.01). While 21.7% of patients in the placebo group experienced regular intestinal habits after 4 wk, this improvement was greater for patients treated with 40 mg OB (P < 0.01 vs placebo). Furthermore, a dose-dependent reduction in frequency of diarrhoea (χ(2)-test for trend = 11.5, P < 0.001) and an increase in normal stool frequency was observed. Combining individual variables into a global discomfort index revealed significant improvement among increasing OB doses, favouring 40 mg (P = 0.013) and 80 mg OB (P = 0.001) over placebo. No difference was observed between frequency of adverse events for placebo vs OB. This dose-ranging study demonstrates that OB at 40 and 80 mg can improve individual and global

    Vitamin K is essential for bone health, but the effects of low-dose vitamin K intake in Japanese subjects remain unclear. We investigated the effective minimum daily menaquinone-7 dose for improving osteocalcin γ-carboxylation. Study 1 was a double-blind, randomized controlled dose-finding trial; 60 postmenopausal women aged 50-69 y were allocated to one of four dosage group and consumed 0, 50, 100, or 200 μg menaquinone-7 daily for 4 wk, respectively, with a controlled diet in accordance with recommended daily intakes for 2010 in Japan. Study 2 was a double-blind, randomized placebo-controlled trial based on the results of Study 1; 120 subjects aged 20-69 y were allocated to the placebo or MK-7 group and consumed 0 or 100 μg menaquinone-7 daily for 12 wk, respectively. In both studies, circulating carboxylated osteocalcin and undercarboxylated osteocalcin were measured. The carboxylated osteocalcin/undercarboxylated osteocalcin ratio decreased significantly from baseline in the 0 μg menaquinone-7 group, in which subjects consumed the recommended daily intake of vitamin K with vitamin K1 and menaquinone-4 (Study 1). Menaquinone-7 increased the carboxylated osteocalcin/undercarboxylated osteocalcin ratio dose dependently, and significant effects were observed in both the 100 and 200 μg groups compared with the 0 μg group. Undercarboxylated osteocalcin concentrations decreased significantly, and the carboxylated osteocalcin/undercarboxylated osteocalcin ratio increased significantly in the 100 μg menaquinone-7 group compared with the placebo group (Study 2). Daily menaquinone-7 intake ≥100 μg was suggested to improve osteocalcin γ-carboxylation.

    The objective of this study was to investigate the efficacy of pirenzepine in the treatment of clozapine-induced hypersalivation. Pirenzepine is reported to counteract hypersalivation by its selective antagonistic activity on the M4-muscarinic receptor, which is stimulated by clozapine. Twenty patients with clozapine-induced hypersalivation underwent a random-order, double-blind, placebo-controlled, cross-over trial which lasted 8 weeks each for the pirenzepine and placebo investigations, with a 4-week washout period in between. The severity of hypersalivation was assessed using an objective measure: saliva production monitored through the diameter of wetted surface on tissue paper placed over the patient's pillow. Our study showed that pirenzepine had no significant therapeutic effect on hypersalivation compared with placebo, suggesting that hypersalivation induced by clozapine might have a neurobiological basis other than the M4-muscarinic receptor.

    The efficacy of estrogen replacement therapy (ERT) for mood disturbances associated with menopause has yet to be firmly established. The objective of this study was to investigate the efficacy of ERT for improving mood and anxiety of non-depressive postmenopausal women. This double-blind, randomized, placebo-controlled study involved two treatment groups: one receiving conjugated equine estrogens (CEEs; 0.625 mg/day) and the other placebo, for six cycles of 28 days each. Subjects were hysterectomized, healthy, non-depressive (according to Schedule for Affective Disorders and Schizophrenia, Life Time Version [SADS-L]) women. Depressive and anxiety symptoms were assessed with the Beck Depression Inventory (BDI), and the Hamilton Anxiety Scale (HAMA), respectively. The Profile of Mood States (POMS) and other scales were used to characterize symptoms. In both groups, BDI scores were significantly lower at cycles 1, 2, 3, and 6, compared with baseline assessments (pwomen.

    Racemic mefloquine is a highly effective antimalarial whose clinical utility has been compromised by its association with neuropsychiatric and gastrointestinal side effects. It is hypothesized that the cause of the side effects may reside in the (-) enantiomer. We sought to compare the safety, tolerability and pharmacokinetic profile of (+)-mefloquine with racemic mefloquine in a randomized, ascending-dose, double-blind, active and placebo-controlled, parallel cohort study in healthy male and female adult volunteers. Although differing in its manifestations, both study drugs displayed a substantially worse tolerability profile compared with placebo. The systemic clearance was slower for (-)-mefloquine than (+)-mefloquine. Thus, (+)-mefloquine has a different safety and tolerability profile compared with racemic mefloquine but its global safety profile is not superior and replacement of the currently used antimalarial drug with (+)-mefloquine is not warranted.

    Full Text Available Abstract Background Molecular hydrogen has prominent effects on more than 30 animal models especially of oxidative stress-mediated diseases and inflammatory diseases. In addition, hydrogen effects on humans have been reported in diabetes mellitus type 2, hemodialysis, metabolic syndrome, radiotherapy for liver cancer, and brain stem infarction. Hydrogen effects are ascribed to specific radical-scavenging activities that eliminate hydroxyl radical and peroxynitrite, and also to signal-modulating activities, but the detailed molecular mechanisms still remain elusive. Hydrogen is a safe molecule that is largely produced by intestinal bacteria in rodents and humans, and no adverse effects have been documented. Methods We performed open-label trial of drinking 1.0 liter per day of hydrogen-enriched water for 12 weeks in five patients with progressive muscular dystrophy (PMD, four patients with polymyositis/dermatomyositis (PM/DM, and five patients with mitochondrial myopathies (MM, and measured 18 serum parameters as well as urinary 8-isoprostane every 4 weeks. We next conducted randomized, double-blind, placebo-controlled, crossover trial of 0.5 liter per day of hydrogen-enriched water or placebo water for 8 weeks in 10 patients with DM and 12 patients with MM, and measured 18 serum parameters every 4 weeks. Results In the open-label trial, no objective improvement or worsening of clinical symptoms was observed. We, however, observed significant effects in lactate-to-pyruvate ratios in PMD and MM, fasting blood glucose in PMD, serum matrix metalloproteinase-3 (MMP3 in PM/DM, and serum triglycerides in PM/DM. In the double-blind trial, no objective clinical effects were observed, but a significant improvement was detected in lactate in MM. Lactate-to-pyruvate ratios in MM and MMP3 in DM also exhibited favorable responses but without statistical significance. No adverse effect was observed in either trial except for hypoglycemic episodes in an insulin

    Pregnenolone (PREG) and dehydroepiandrosterone (DHEA) are reported to have a modulatory effect on neuronal excitability, synaptic plasticity, and response to stress; they are associated with mood regulation and cognitive performance. We investigated the influence of PREG and DHEA on psychotic symptoms and cognitive functioning as an add-on to ongoing antipsychotic treatment of patients with chronic schizophrenia or schizoaffective disorder. This 8-week, double-blind, randomized, placebo-controlled, 2-center study compared 30 mg/d of PREG (PREG-30), 200 mg/d of PREG (PREG-200), 400 mg/d of DHEA, and placebo as an adjunctive treatment of 58 chronic schizophrenia or schizoaffective disorder patients (DSM-IV). The data were collected from February 2005 until June 2007. The outcome measures were symptomatic and neurocognitive changes, functioning, and tolerability as assessed primarily by the Clinical Global Impressions-Severity of Illness scale and the Positive and Negative Syndrome Scale. Analyses are presented for 44 patients who completed 8 weeks of treatment and for 14 noncompleters. Compared with subjects who received placebo, those administered PREG-30 had significant reductions in positive symptom scores and extrapyramidal side effects (EPS) and improvement in attention and working memory performance, whereas subjects treated with PREG-200 did not differ on outcome variable scores for the study period. The general psychopathology severity and general functioning of patients receiving placebo and PREG-30 improved more than that of those subjects treated with DHEA, while EPS improved more in subjects treated with DHEA than in patients receiving placebo. Negative symptoms and akathisia were not significantly benefited by any treatment. The administration of PREG and DHEA was well tolerated. Low-dose PREG augmentation demonstrated significant amelioration of positive symptoms and EPS and improvement in attention and working memory performance of schizophrenia and

    Full Text Available Background: The objective of this study was to evaluate the reliability of the postoperative pain control using adductor canal block (ACB compared that using the femoral nerve block (FNB in patients with anterior cruciate ligament reconstructions (ACLR. Materials and methods: One hundred and twenty-eight patients who had been scheduled to patellar graft ACLR were included in this double blind study, and were randomly allocated into two groups; group ACB and group FNB (64 patients each. All patients received general anesthesia. At the end of the surgery, patients in group FNB received a FNB and those in group ACB received an ACB. The postoperative pain (visual analog scale [VAS] and muscle weakness were assessed in the postoperative care unit and every 6 h thereafter for 24 h. The total morphine requirements were also recorded. Results: Patients in group ACB had significantly higher VAS (at 18 h and 24 h, higher morphine consumption, but significantly less quadriceps weakness than those in group FNB. Conclusion: In patients with patellar graft ACLR, the ACB can maintain a higher quadriceps power, but with lesser analgesia compared with the FNB.

    To determine the value of clindamycin prophylaxis in the prevention of postoperative wound infections in patients undergoing endodontic surgery. This study included 256 patients undergoing endodontic surgery in a prospective double-blind placebo-controlled trial comparing oral administration of an oral placebo versus a preoperative 600 mg dose of clindamycin. After randomization the study medication was administered orally 1 h before surgery in a double-blind fashion. For a period of 4 weeks the postoperative course was observed according to clinical parameters of infection. Primary end-point was infection at the surgical site. The mean age of the study population was 44.4 years (SD 11.4, range 18-82 years) with a sex distribution of 147 females (47.4%) and 109 males (42.6%). Mean age of the patients in the clindamycin group was 44.7 years (SD 12.0), and the mean age in the placebo group was 44.1 years (SD 10.8) (P = 0.49). In the clindamycin group, the mean duration of surgery was 32.3 min (SD 8.8) and in the placebo group the mean duration of surgery was 32.5 min (SD 8.4) (P = 0.89). Two infections [1.6%; 95 confidence interval (CI): 0.48-4.72] were identified in the clindamycin group and four (3.2%; 95 CI: 0.42-1.33) in the placebo group (P = 0.448). No statistically significant difference was found between clindamycin prophylaxis and placebo with regard to the prevention of postoperative infection in endodontic surgical procedures.

    Transcutaneous electrical nerve stimulation (TENS) is a noninvasive alternative to traditional pain treatments. TENS has been studied in the past as a pain reduction modality in colonoscopy with limited success. Reviews and meta-analysis have shown that the inconclusive results of TENS may be due to the lack of randomized controlled trials and the difficulty in defining precise output parameters. The objective of this double-blind randomized placebo-controlled trial was to investigate the pain-relieving effect of a new application of TENS in unsedated screening colonoscopy. Ninety patients undergoing unsedated screening colonoscopy were randomly allocated to one of three groups: a control group (n=30), a group to receive active TENS (n=30), or a group to receive placebo TENS (n=30). A visual analogue scale (VAS) and a five-point Likert scale were used to assess pain 5 min into the procedure and at the end of the procedure. The patient's bloating sensation during colonoscopy and the effect on the duration of the procedure were also evaluated. Throughout the procedure, the active TENS group experienced a VAS pain score reduction ≥50% compared to the placebo TENS group (PTENS group compared to the placebo TENS and control groups (P=0.009). No significant differences were found between the study groups as to the bloating sensation and the duration of the procedure. We conclude that TENS can be used as a pain relief therapy in unsedated screening colonoscopy.

    Resistant hypertension is defined as an uncontrolled blood pressure despite treatment at best-tolerated doses with at least three antihypertensive agents including a diuretic. It is an emerging public health problem. At present clinical trial data on management of resistant hypertension is limited. Management is largely based on observational studies and expert opinions. Propranolol is a nonselective beta blocker. Several studies have confirmed that propranolol has a significant hypotensive action, both when used alone and as an adjuvant therapy. At present there are no prospective, randomized, clinical studies evaluating the effectiveness of propranolol in patients with resistant hypertension. Therefore, we have designed a prospective randomized trial to evaluate the safety and efficacy of propranolol in patients with resistant hypertension. The study will be conducted as a randomized, double-blind, placebo-controlled clinical trial for a period of 3 months. The study has been approved by the Ethics Review Committee of the Faculty of Medicine, University of Colombo. A total of 200 adults with resistant hypertension will be recruited for the study. They will be randomly assigned to the test and placebo groups on a 1:1 ratio. The test group will receive propranolol 40 mg three times a day and the control group will receive an identical placebo capsule. The study drugs will be double blinded to both investigators and subjects. The visits and the evaluations will be done as follows: screening (visit 0), 1 month (visit 1), 2 months (visit 2) and 3 months (visit 3). The primary outcomes of the study is to find a statistically significant difference between the fall in mean systolic and mean diastolic blood pressure measured by ABPM (ambulatory blood pressure monitoring) from baseline between the two groups. Data will be analyzed using SPSS v16. To our knowledge this is one of the first randomized controlled trials evaluating the effects of propranolol in resistant

    Full Text Available Context: Many techniques are used for sedation of colonoscopies. Patient-controlled sedation (PCS is utilizing many drugs or drug combinations. Aims: The aim of this study is to compare the safety and feasibility of propofol/remifentanil versus propofol/alfentanil given to sedate patients undergoing outpatient colonoscopies through a patient-controlled technique. Settings and Design: Controlled randomized and double-blind study. Materials and Methods: A total of 80 patients were randomly divided into two groups; PA group received a combination of propofol/alfentanil and PR group received propofol/remifentanil combination. Patients were monitored for heart rate (HR, blood pressure (BP, oxygen saturation, and Ramsay sedation scale (RSS. Times of the following events were recorded; initiation of sedation, insertion and removal of the colonoscope, recovery and discharge. Five intervals were calculated; time to sedation, procedure time, postprocedure time, procedure room time, and postanesthesia care unit (PACU time. Endoscopist and patient satisfaction scores were obtained. Statistical Analysis Used: Unpaired Student′s t-test was used to compare between the two groups. Paired Student′s t-test was used to compare baseline readings with readings after 30 min of sedation in the same group when needed. Results: Both groups showed slowing of the HR and decrease in mean arterial BP. HR and mean arterial BP were significantly lower 5 and 10 min after initiation of sedation in PR group when compared with PA group. Both HR and mean arterial BP returned to presedation readings 30 min after initiation of sedation in PR group but not in PA group. No differences between the two groups concerning oxygen saturation, RSS, endoscopist and patient satisfaction scores. Postprocedure and PACU times were significantly prolonged in PA group. Conclusion: PCS with either remifentanil/propofol or alfentanil/propofol for patients undergoing outpatient colonoscopy is safe

    Background: Ultrasound-guided transversus abdominis plane (TAP) block is done as a part of multimodal analgesia for pain relief after abdominal surgeries. This prospective randomized, double-blind, placebo-controlled trial was conducted to evaluate the postoperative analgesic efficacy of bilateral TAP block in patients undergoing midline colorectal surgeries using ropivacaine. Materials and Methods: Eighty patients scheduled for elective colorectal surgeries involving midline abdominal wall incision under general anesthesia were enrolled in this prospective randomized controlled trial. Group A received TAP block with 20 ml of 0.2% ropivacaine on either side of the abdominal wall, and Group B received 20 ml of normal saline. The time to request for rescue analgesia, total analgesic consumption in 24 h, and satisfaction with the anesthetic technique were assessed. Results: The mean visual analog scale scores at rest and on coughing were higher in control group (P > 0.05). Time (min) to request for the first rescue analgesia was prolonged in study group compared to control group (P tramadol consumption in 24 h postoperatively was significantly high in control group (P 0.05). The level of satisfaction concerning postoperative pain control/anesthetic technique was higher in study group (P tramadol requirements, reduction in postoperative pain scores, and increased time to first request for further analgesia, both at rest and on movement.

    Full Text Available Abstract Background Neurotoxicity caused by treatment for a brain tumor is a major cause of neurocognitive decline in survivors. Studies have shown that neurofeedback may enhance neurocognitive functioning. This paper describes the protocol of the PRISMA study, a randomized controlled trial to investigate the efficacy of neurofeedback to improve neurocognitive functioning in children treated for a brain tumor. Methods/Design Efficacy of neurofeedback will be compared to placebo training in a randomized controlled double-blind trial. A total of 70 brain tumor survivors in the age range of 8 to 18 years will be recruited. Inclusion also requires caregiver-reported neurocognitive problems and being off treatment for more than two years. A group of 35 healthy siblings will be included as the control group. On the basis of a qEEG patients will be assigned to one of three treatment protocols. Thereafter patients will be randomized to receive either neurofeedback training (n=35 or placebo training (n=35. Neurocognitive tests, and questionnaires administered to the patient, caregivers, and teacher, will be used to evaluate pre- and post-intervention functioning, as well as at 6-month follow-up. Siblings will be administered the same tests and questionnaires once. Discussion If neurofeedback proves to be effective for pediatric brain tumor survivors, this can be a valuable addition to the scarce interventions available to improve neurocognitive and psychosocial functioning.

    Background Chronic migraine (CM) is problematic, and there are few effective treatments. Recently, it has been hypothesized that glial activation may be a contributor to migraine; therefore, this study investigated whether the potential glial inhibitor, ibudilast, could attenuate CM. Methods The study was of double-blind, randomized, placebo-controlled, two-period crossover design. Participants were randomized to receive either ibudilast (40 mg twice daily) or placebo treatment for 8 weeks. Subsequently, the participants underwent a 4-week washout period followed by a second 8-week treatment block with the alternative treatment. CM participants completed a headache diary 4 weeks before randomization throughout both treatment periods and 4 weeks after treatment. Questionnaires assessing quality of life and cutaneous allodynia were collected on eight occasions throughout the study. Results A total of 33 participants were randomized, and 14 participants completed the study. Ibudilast was generally well tolerated with mild, transient adverse events, principally nausea. Eight weeks of ibudilast treatment did not reduce the frequency of moderate to severe headache or of secondary outcome measures such as headache index, intake of symptomatic medications, quality of life or change in cutaneous allodynia. Conclusion Using the current regimen, ibudilast does not improve migraine with CM participants. PMID:27826212

    2012-01-31

    BACKGROUND: A eutectic mixture of lidocaine and prilocaine (EMLA) has been shown to be effective in reducing pain from needle sticks, including those associated with blood sampling and intravenous insertion. OBJECTIVE: To evaluate the effectiveness of EMLA cream applied before needle puncture for local anesthetic administration before minor surgical procedures in this double-blind, randomized, controlled, parallel-group study. MATERIALS AND METHODS: Patients were randomly assigned to receive EMLA or placebo cream (Aqueous) applied under an occlusive dressing. After the procedure, patients were asked to rate the needle prick and procedure pain on a visual analog scale (0=no pain; 10=maximum pain). RESULTS: A total of 94 minor surgical procedures (49 in EMLA and 45 in control) were performed. The mean needle-stick pain score in the EMLA group was significantly lower than in the control group (2.7 vs. 5.7, p<.001, Mann-Whitney U-test). There was also significantly lower procedure pain in the EMLA group than in the control group (0.83 vs. 1.86, p=.009). There were no complications associated with the use of EMLA. CONCLUSION: EMLA effectively reduces the preprocedural needle-stick pain and procedural pain associated with minor surgical procedures.

    [Purpose] Improved gait efficiency is one of the goals of therapy for children with cerebral palsy (CP). Postural insoles can allow more efficient gait by improving biomechanical alignment. The aim of the present study was to assess the effect of postural insoles on gait performance of children with CP classified as levels I or II of the Gross Motor Function Classification System (GMFCS). [Subjects and Methods] the study was a randomized controlled double-blind clinical trial. After meeting the legal aspects and the eligibility criteria, 10 children between four and 12 years old were randomly divided into a two groups: a control group (n=5), and an experimental group (n=5). Children in the control group used a placebo insoles, and children in the experimental group used postural insoles. Evaluation consisted of three-dimensional gait analysis under three conditions: barefoot, shoes without insoles and shoes with postural insoles or shoes with placebo insoles. [Results] Regarding the immediate effects of insole use, significant improvements in gait velocity and cadence were observed in the experimental group in comparison to the control group. [Conclusion] The use of postural insoles led to improvements in gait velocity and cadence of the children with cerebral palsy classified as levels I or II of the GMFCS.

    Aim To determine the effects of hyoscine-N-butyl bromide (HBB) rectal suppository on labor progress in primigravid women. Methods A randomized double-blind placebo-controlled clinical trial was carried out on 130 primigravid women admitted for spontaneous labor. The women were recruited based on the inclusion and exclusion criteria and randomized into the experimental (n = 65) and control group (n = 65). In the beginning of the active phase of labor, 20 mg of HBB rectal suppository was administered to the experimental group, while a placebo suppository was administered to the control group. Cervical dilatation and duration of active phase and second stage of labor were recorded. Results The rate of cervical dilatation was 2.6 cm/h in the experimental and 1.5 cm/h in the control group (P suppository in the active management of labor can shorten both the active phase and second stage of labor without significant side-effects.

    The scope of transdermal analgesics have been limited to pain control following local trauma, muscle spasm, minor esthetic surgeries, or sports-related injuries. Its scope of application can be extended in the field of dentistry and minor oral surgical procedures. A total of 40 healthy patients between the age of 18 and 50 years with deeply carious, nontender mandibular molar tooth deemed unsalvageable which was indicated for extraction were taken into study of which subjects were divided into cases and controls. The data were analyzed with chi-square test and Mann-Whitney U test; the chi-square test showed significant association with expected outcome in visual analog scale pain scores, the two groups at 6th and 12th hour. A Mann-Whitney U test was performed to identify strength of association between two groups where there were significant association between all parameters except for pain interference with routine activities and dental health status(0.022, 0.001); the differences between two groups in these parameters were significant (Transdermal route seems to be comparable to oral diclofenac in post-extraction pain relief; further studies are required to confirm the results and safety for its use in various other dental situations.

Photobiomodulation therapy improves performance and accelerates recovery of high-level rugby players in field test: A randomized, crossover, double-blind, placebo-controlled clinical study. J Strength Cond Res 30(12): 3329-3338, 2016-Although growing evidence supports the use of photobiomodulation therapy (PBMT) for performance and recovery enhancement, there have only been laboratory-controlled studies. Therefore, the aim of this study was to analyze the effects of PBMT in performance and recovery of high-level rugby players during an anaerobic field test. Twelve male high-level rugby athletes were recruited in this randomized, crossover, double-blinded, placebo-controlled trial. No interventions were performed before the Bangsbo sprint test (BST) at familiarization phase (week 1); at weeks 2 and 3, pre-exercise PBMT or placebo were randomly applied to each athlete. Photobiomodulation therapy irradiation was performed at 17 sites of each lower limb, employing a cluster with 12 diodes (4 laser diodes of 905 nm, 4 light emitting diodes [LEDs] of 875 nm, and 4 LEDs of 640 nm, 30 J per site, manufactured by Multi Radiance Medical). Average time of sprints, best time of sprints, and fatigue index were obtained from BST. Blood lactate levels were assessed at baseline, and at 3, 10, 30, and 60 minutes after BST. Athletes' perceived fatigue was also assessed through a questionnaire. Photobiomodulation therapy significantly (p ≤ 0.05) improved the average time of sprints and fatigue index in BST. Photobiomodulation therapy significantly decreased percentage of change in blood lactate levels (p ≤ 0.05) and perceived fatigue (p ≤ 0.05). Pre-exercise PBMT with the combination of super-pulsed laser (low-level laser), red LEDs, and infrared LEDs can enhance performance

    Spontaneous bacterial peritonitis (SBP) may occur despite antibiotic prophylaxis. We investigated whether the addition of probiotics to norfloxacin enhances its efficacy in the prevention of SBP. A double-blind, randomized-controlled trial was conducted among consecutive cirrhotic patients who had either recovered from SBP (secondary prophylaxis) or who were at a high risk for the development of SBP (low ascitic fluid protein or serum bilirubin ≥ 2.5 mg/dl; primary prophylaxis). Norfloxacin 400 mg/day with probiotics capsules (Enterococcus faecalis JPC 30 million, Clostridium butyricum 2 million, Bacillus mesentericus JPC 1 million, Bacillus coagulans 50 million spores) at a dose of two capsules three times daily (group 1) or norfloxacin with a placebo (group 2) was given and the occurrence of SBP within a period of 6 months (primary endpoint) or side-effects of therapy and mortality (secondary endpoints) were recorded. From April 2005 through August 2007, 110 patients were randomized to group 1 (n=55) or group 2 (n=55) and 45 (82%) and 43 (78%) of them completed the trial, respectively. The baseline characteristics were comparable. On intention-to-treat analysis, the cumulative probability of treatment failures was similar in both the groups [19/55 (34%) in group 1 vs. 20/55 (36%) in group 2, P=0.840]. The cumulative probability of mortality was also similar [13/45 (29%) in group 1 vs. 14/43 (32%) in group 2, P=0.834]. The frequency of side-effects was also comparable. In subgroup analyses, the frequencies of SBP and deaths were similar in the two groups in the subgroups of primary and secondary prophylaxes. The presence of encephalopathy and serum bilirubin of greater than 3.65 mg/dl were found to predict mortality independently. The addition of probiotics to norfloxacin does not improve its efficacy in primary or secondary prophylaxis of SBP or in reducing the mortality in cirrhotic patients with ascites.

    Full Text Available Aims and Objectives: To evaluate and compare the efficacy of diclofenac and meloxicam as mucoadhesive patches in dental pain management. Materials and Method: This study was conducted among 45 adult patients of either sex, who were diagnosed with dental pain and were attending the outpatient department. Written informed consent was obtained from all the patients. A 1 × 1 cm2 mucoadhesive patch of any one (diclofenac, meloxicam or placebo was applied on the attached gingival region of the tooth with pain. Pain was recorded using a ten point visual analog scale (VAS score at every 5 min for 30 min. Pain was measured and compared before and after the application of the patch. Results: The results showed that patients with diclofenac patch gained mean pain reduction from 6 ± 1.54 mm to 2.60 ± 1.32 mm after 30 min (P 0.05. The maximum pain reduction was seen with meloxicam patch. Conclusion: Transmucosal mucoadhesive analgesic patches are a better alternative to oral analgesics to control dental pain. Hence, routine use of mucoadhesive analgesic patch for dental pain reduction is recommended in day to day practice.

    Full Text Available ABSTRACT BACKGROUND: Succinylcholine is commonly used to achieve profound neuromuscular blockade of rapid onset and short duration. OBJECTIVE: The present study compared the efficacy of pregabalin for prevention of succinylcholine-induced fasciculation and myalgia. DESIGN: Prospective, randomized, placebo controlled, double blinded study. MATERIALS AND METHODS: Patients of both genders undergoing elective spine surgery were randomly assigned to two groups. Patients in Group P (pregabalin group received 150 mg of pregabalin orally 1 h prior to induction of anesthesia with sips of water and patients in Group C (control group received placebo. Anesthesia was induced with fentanyl 1.5 mcg/kg, propofol 1.5-2.0 mg/kg followed by succinylcholine 1.5 mg/kg. The intensity of fasciculations was assessed by an observer blinded to the group allotment of the patient on a 4-point scale. A blinded observer recorded postoperative myalgia grade after 24 h of surgery. Patients were provided patient-controlled analgesia with fentanyl for postoperative pain relief. RESULTS: Demographic data of both groups were comparable (p > 0.05. The incidence of muscle fasciculation's was not significant between two groups (p = 0.707, while more patients in group C had moderate to severe fasciculation's compared to group P (p = 0.028. The incidence and severity of myalgia were significantly lower in group P (p < 0.05. CONCLUSION: Pregabalin 150 mg prevents succinylcholine-induced fasciculations and myalgia and also decreases the fentanyl consumption in elective sine surgery.

    Lidocaine reduces pain that occurs upon the intravenous injection of propofol. But, there are few non-pharmacological nursing interventions to reduce propofol injection pain. To compare the effects of lidocaine pre-administration and local warming of the intravenous access site on propofol injection pain. Prospective, double-blind, randomized controlled trial. The 555 bed, non-teaching National Cancer Center in Kyunggido, South Korea. A total of 96 patients who underwent thyroidectomy under total intravenous general anesthesia with propofol were randomly allocated to the control, lidocaine pre-administration (LA) or local warming (LW) group. All three groups received 2% propofol with an effect-site target at 3μg/mL for induction dose. The control group received 2% propofol with no intervention. The lidocaine pre-administration group received 2% propofol 30s after 1% lidocaine 30mg. The local warming group received 2% propofol after warming of the intravenous access site for 1min using 43°C forced air. Propofol injection pain was assessed by four-point verbal categorial scoring (VCS), numerical rating scale (NRS) and surgical pleth index (SPI). Pain VCS of the LA group (mean±SD, 1.11±0.45) was significantly reduced (U=-3.92, plidocaine pre-administration. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Common infectious diseases, such as diarrhea, are still the major cause of death in children under 5-years-old, particularly in developing countries. It is known that there is a close relationship between nutrition and immune function. To evaluate the effect of a growing-up milk containing synbiotics on immune function and child growth, we conducted a cluster randomized, multicenter, double-blind, placebo controlled clinical trial in children between 18 and 36 months of age in Vietnam. Eligible children from eight and seven kindergartens were randomly assigned to receive test and isocaloric/ isoproteic control milk, respectively, for 5 months. We found that the blood immunoglobulin A (IgA) level and growth parameters were increased in the test group. Compared to the control group, there was also a trend of decreased vitamin A deficiency and fewer adverse events in the test group. These data suggest that a growing-up milk containing synbiotics may be useful in supporting immune function and promoting growth in children.

    Background Preemptive analgesia is considered an alternative for treating the postsurgical pain of third molar removal. The aim of this study was to evaluate the preemptive analgesic efficacy of oral ketorolac versus intramuscular tramadol after a mandibular third molar surgery. Material and Methods A parallel, double-blind, randomized, placebo-controlled clinical trial was carried out. Thirty patients were randomized into two treatment groups using a series of random numbers: Group A, oral ketorolac 10 mg plus intramuscular placebo (1 mL saline solution); or Group B, oral placebo (similar tablet to oral ketorolac) plus intramuscular tramadol 50 mg diluted in 1 mL saline solution. These treatments were given 30 min before the surgery. We evaluated the time of first analgesic rescue medication, pain intensity, total analgesic consumption and adverse effects. Results Patients taking oral ketorolac had longer time of analgesic covering and less postoperative pain when compared with patients receiving intramuscular tramadol. Conclusions According to the VAS and AUC results, this study suggests that 10 mg of oral ketorolac had superior analgesic effect than 50 mg of tramadol when administered before a mandibular third molar surgery. Key words:Ketorolac, tramadol, third molar surgery, pain, preemptive analgesia. PMID:27475688

    Full Text Available Abstract Background Lumbar spinal stenosis is one of the most common causes of low back pain among older adults and can cause significant disability. Despite its prevalence, treatment of spinal stenosis symptoms remains controversial. Epidural steroid injections are used with increasing frequency as a less invasive, potentially safer, and more cost-effective treatment than surgery. However, there is a lack of data to judge the effectiveness and safety of epidural steroid injections for spinal stenosis. We describe our prospective, double-blind, randomized controlled trial that tests the hypothesis that epidural injections with steroids plus local anesthetic are more effective than epidural injections of local anesthetic alone in improving pain and function among older adults with lumbar spinal stenosis. Methods We will recruit up to 400 patients with lumbar central canal spinal stenosis from at least 9 clinical sites over 2 years. Patients with spinal instability who require surgical fusion, a history of prior lumbar surgery, or prior epidural steroid injection within the past 6 months are excluded. Participants are randomly assigned to receive either ESI with local anesthetic or the control intervention (epidural injections with local anesthetic alone. Subjects receive up to 2 injections prior to the primary endpoint at 6 weeks, at which time they may choose to crossover to the other intervention. Participants complete validated, standardized measures of pain, functional disability, and health-related quality of life at baseline and at 3 weeks, 6 weeks, and 3, 6, and 12 months after randomization. The primary outcomes are Roland-Morris Disability Questionnaire and a numerical rating scale measure of pain intensity at 6 weeks. In order to better understand their safety, we also measure cortisol, HbA1c, fasting blood glucose, weight, and blood pressure at baseline, and at 3 and 6 weeks post-injection. We also obtain data on resource utilization

    Testosterone replacement therapy (TRT) has been investigated in older men as a preventative treatment against Alzheimer's disease and dementia. However, previous studies have been contradictory. We assessed TRT physiological effects in 44 older men (aged 61 ± 7.7 years) with subjective memory complaints using a double blind, randomized, crossover, placebo-controlled study. Participants were randomized into 2 groups, one group received transdermal testosterone (50 mg) daily for 24 weeks, followed by a 4 week wash-out period, then 24 weeks of placebo; the other group received the reverse treatment. Blood evaluation revealed significant increases in total testosterone, free (calculated) testosterone, dihydrotestosterone, and a decrease in luteinizing hormone levels (p<0.001) following TRT. Although there were significant increases in red blood cell counts, hemoglobin and prostate specific antigen levels following TRT, they remained within normal ranges. No significant differences in plasma amyloid beta, estradiol, sex hormone binding globulin, insulin levels, body fat percentage, or body mass index were detected. This is the first carefully controlled study that has investigated the influence of TRT in Indonesian men on blood biomarkers linked to dementia risk. Our study suggests TRT is safe and well-tolerated in this Indonesian cohort, yet longitudinal studies with larger cohorts are needed to assess TRT further, and to establish whether TRT reduces dementia risk.

    Cerebrolysin has exhibited neuroprotective as well as neurotrophic properties in various animal models of cerebral ischaemia and has shown clinical efficacy and good safety in several small controlled clinical studies in ischaemic stroke. Therefore, a large double-blind placebo-controlled randomized clinical trial was launched in Asia to prove the validity of this treatment strategy. In the more than 50 participating centres patients with acute ischemic hemispheric stroke are randomized within 12 hours of symptoms onset to treatment (30 ml Cerebrolysin diluted in physiologic saline) or placebo (saline) given as intravenous infusion once daily added to standard care for 10 days. The patients are followed with regular visits for 90 days. Efficacy is evaluated on day 90 by three outcome scales - modified Rankin Scale, Barthel Index and NIH Stroke Scale - combined to single global directional test. Additionally, adverse events are documented to prove safety. In this study a total of 1060 patients will be included and analysis of data will be completed in 2010. If positive, this trial will add an effective strategy to the treatment of acute ischaemic stroke.

    The aim of this study was to compare the therapeutic efficacy of alginate-based reflux suppressant and magnesium-aluminium antacid gel for treatment of heartburn in pregnancy. A double-blinded, randomized, controlled trial was conducted. One hundred pregnant women at less than 36 weeks gestation with heartburn at least twice per week were randomized to either alginate-based reflux suppressant or to magnesium-aluminium antacid gel. Details of heartburn were recorded before beginning the treatment and the second week of study. Primary outcome measure was the improvement of heartburn frequency after treatment and secondary outcome were the improvement of heartburn intensity, quality of life, maternal satisfaction, maternal side effects, pregnancy and neonatal outcomes. There was no difference between treatment and control groups in improvement of heartburn frequency (80% vs 88%, p = 0.275), 50% reduction of frequency of heartburn (56% vs 52%, p = 0.688), improvement of heartburn intensity (92% vs 92%, p = 1.000) and 50% reduction of heartburn intensity (68% vs 80% cases, p = 0.075). There were also no significant differences in quality of life, maternal satisfaction, maternal side effects, pregnancy and neonatal outcomes. Alginate-based reflux suppressant was not different from magnesium-aluminium antacid gel in the treatment of heartburn in pregnancy. PMID:28317885

    The use of prophylactic antibiotics to reduce postoperative complications in third molar surgery remains controversial. The study was a prospective, randomized, double blind, placebo-controlled clinical trial. 100 patients were randomly assigned to two groups. Each patient acted as their own control using the split-mouth technique. Two unilateral impacted third molars were removed under antibiotic cover and the other two were removed without antibiotic cover. The first group received antibiotics on the first surgical visit. On the second surgical visit (after 3 weeks), placebo capsules were given or vice versa. The second group received antibiotics with continued therapy for 2 days on the first surgical visit and on the second surgical visit (after 3 weeks) placebo capsules were given or vice versa. Pain, swelling, infection, trismus and temperature were recorded on days 3, 7 and 14 after surgery. Of 380 impactions, 6 sockets (2%) became infected. There was no statistically significant difference in the infection rate, pain, swelling, trismus, and temperature between the two groups (p>0.05). Results of the study showed that prophylactic antibiotics did not have a statistically significant effect on postoperative infections in third molar surgery and should not be routinely administered when third molars are removed in non-immunocompromised patients.

    Herpes labialis affects one third of the population. We evaluated the topical application of an antiviral compound, hydroxypropyl-β-cyclodextrin (2-HPβCD), in reducing herpes labialis relapses. In this double-blind, randomized, placebo-controlled trial, 40 patients were randomized to a polyethylene glycol (PEG) formulation containing 20% 2-HPβCD or to a vehicle control arm. The gel was applied to the lips twice daily for 6 months. The primary objective was reducing herpes relapses. Surprisingly, the drug group had significantly more relapses than the vehicle group (p = 0.003). While the median numbers of relapses in the preceding year were 12 in the vehicle group and 10 in the drug group, both groups experienced very few relapses during the 6-month treatment period, with a median of 0 in the vehicle group and a median of 2 in the drug group. The impressive reduction of relapses in both groups may be due to a placebo effect or due to the topical treatment with PEG.

    We conducted a 16-week double-blind randomized controlled single-center trial to evaluate the safety and efficacy of dermal rice bran supercritical CO2 extract (RB-SCE) in the treatment of androgenic alopecia. Fifty alopecia patients were randomly assigned to the experimental and placebo groups. The experimental group received a dermal application of 0.5% RB-SCE (8 mL/d) to the head skin for 16 weeks while the control group received a dermal application of placebo. Changes in hair count, diameter, and density were evaluated with a Folliscope(®). Patient satisfaction was evaluated via questionnaire and clinical photographs were rated by dermatologists. The results showed that RB-SCE significantly increased hair density and hair diameter in male subjects. Patient satisfaction and the evaluation of photographs by dermatologists also confirmed the effectiveness of RB-SCE in the treatment of alopecia. No adverse reactions related to RB-SCE were reported. Therefore, RB-SCE shows promise for use in functional cosmetics and pharmaceuticals.

    Vaginal atrophy is one of the main concerns of postmenopausal women. The aim of the present study was to investigate the effect of fennel vaginal cream on vaginal atrophy in postmenopausal women in Ahvaz, Iran. This double-blind randomized controlled trial was conducted on 60 postmenopausal women (45-65 years of age) in Ahvaz, Iran. The study participants were randomly divided into one of two groups, receiving either a placebo (n=30) or fennel 5% vaginal cream (n=30) administered as one application per day (5g/day) for 8 weeks. The vaginal pH and maturation vaginal index (MVI) were measured at baseline and 8 weeks after the intervention, while the vaginal atrophy symptoms was measured at baseline and at 2, 4, and 8 weeks after the intervention. The data were analyzed using the independent t-test, chi-square test, paired sample t-test, and the generalized estimating equation. The number of superficial cells increased significantly in the fennel group after 8 weeks compared to the control group (76.1±15.3 vs. 11.8±8, peffective means to manage the symptoms of vaginal atrophy in postmenopausal women and is devoid of side effects. Larger studies are necessary to confirm the positive impact of fennel for vaginal conditions occurring among postmenopausal women. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Hyperlipidemia is associated with increased risk of atherosclerosis; therefore, control of this risk factor is very important in preventing atherosclerosis. Cucumber (Cucumis sativus) seed is used traditionally as a lipid-lowering nutritional supplement. The aim of this study was to evaluate the effect of cucumber seed extract on serum lipid profile in adult patients with mild hyperlipidemia. In a randomized double-blind placebo-controlled clinical trial, hyperlipidemic patients with inclusion criteria were randomly and equally assigned to either Cucumis or placebo groups and used one medicinal or placebo capsule, respectively, once daily with food for 6 wk. Body mass index (BMI) as well as fasting serum levels of total cholesterol, triglycerides (TG), low-density lipoprotein (LDL-C), and high-density lipoprotein (HDL-C) were measured for all patients pre- and post-intervention and finally the changes were compared between the groups. Twenty-four patients in Cucumis group and 23 patients in placebo group completed the study. Cucumis seed extract resulted in significant reduction of total cholesterol (P = 0.016), LDL-C (P < 0.001), TG (P < 0.001), and BMI (P < 0.001) as well as significant increase of HDL-C (P = 0.012) compared to placebo. In conclusion, the consumption of C. sativus seed extract with daily dose of 500 mg results in desirable effects on serum lipid profile in adult hyperlipidemic patients. Therefore, cucumber seed could be considered as a food supplement for treatment of dyslipidemia.

    Full Text Available Background: Dental anxiety is a relatively frequent problem that can lead to more serious problems such as a child entering a vicious cycle as he/she becomes reluctant to accept the required dental treatments. The aim of this randomized double-blind clinical trial study was to evaluate the anxiolytic and sedative effect of pregabalin in children. Materials and Methods: Twenty-five children were randomized to a double-blind placebo-controlled crossover clinical trial. Two visits were scheduled for each patient. At the first visit, 75 mg pregabalin or placebo was given randomly, and the alternative was administered at the next visit. Anxiolytic and sedative effects were measured using the visual analogue scale. The child′s behavior was rated with the Frankl behavioral rating scale and the sedation level during the dental procedure was scored using the Ramsay sedation scale. The unpaired, two-tailed Student′s t-test was used to compare the mean changes of visual analog scale (VAS for anxiety in the pregabalin group with that of the placebo group. A repeated measures MANOVA model was used to detect differences in sedation level in the pregabalin and placebo groups regarding the interaction of 3-time measurements; sub-group analysis was performed using Student′s t-test. The Mann-Whitney U-test was used to analyze the nonparametric data of the Frankl and Ramsay scales. A P < 0.05 was considered significant. Results: The reduction of the VAS-anxiety score from 2 h post-dose was statistically significant in the pregabalin group. From 2 h to 4 h post-dose, the VAS-sedation score increased significantly in the pregabalin group. The child′s behavior rating was not significantly different between the groups. The number of "successful" treatment visits was higher in the pregabalin group compared to the placebo group. Conclusion: Significant anxiolytic and sedative effects can be anticipated 2 h after oral administration of pregabalin without serious

    In Parkinson's disease (PD) reduced dopaminergic activity in the mesocorticolimbic pathway is implied in the pathophysiology of several non-motor symptoms related to mood, motivation and cognition. Insight in the pathophysiology of these syndromes may pave the way for more rational treatments. In a double-blind, randomized, placebo controlled, crossover design with three arms, we studied the effects of a direct dopaminergic challenge with the dopamine 2 receptor agonist pramipexole, an indirect challenge with the dopamine reuptake inhibitor methylphenidate, and placebo on measures of mood, motivation and cognition in 23 agonist-naïve PD patients and 23 healthy controls. Acute challenge with pramipexole had a negative effect on mood and fatigue in both patients and controls. In addition, challenge with pramipexole led to increased anger, fatigue, vigor and tension in healthy control subjects, but not in PD patients. Challenge with methylphenidate had a positive effect on anhedonia and vigor in PD patients. Due to its side effects after a single administration, pramipexole is probably less suitable for acute challenge studies. The acute effects of a methylphenidate challenge on anhedonia and vigor in PD patients make this drug an interesting choice for further studies of the treatment of mood and motivational disorders in this population.

    Full Text Available Abstract Background Arabinogalactan from Larch tree (Larix spp. bark has previously demonstrated immunostimulatory activity. The purpose of this study was to test the hypothesis that ingestion of a proprietary arabinogalactan extract, ResistAid™, would selectively enhance the antibody response to the pneumococcal (pneumonia vaccine in healthy adults. Methods This randomized, double-blind, placebo-controlled, parallel group pilot study included 45 healthy adults who had not previously been vaccinated against Streptococcus pneumoniae. The volunteers began taking the study product or placebo (daily dosage 4.5 g at the screening visit (V1-Day 0 and continued over the entire 72 day study period. After 30 days the subjects received the 23-valent pneumococcal vaccine (V2. They were monitored the following day (V3-Day 31, as well as 21 days (V4-Day 51 and 42 days (V5-Day 72 after vaccination. Responses by the adaptive immune system (antigen specific were measured via pneumococcal IgG antibodies (subtypes 4, 6B, 9V, 14, 18C, 19F, and 23F and salivary IgA levels. Responses by the innate immune system (non-specific were measured via white blood cell counts, inflammatory cytokines and the complement system. Results Vaccination significantly increased pneumococcal IgG levels as expected. The arabinogalactan group demonstrated a statistically significant greater IgG antibody response than the placebo group in two antibodies subtypes (18C and 23F at both Day 51 (p = 0.006 and p = 0.002 and at Day 72 (p = 0.008 and p = 0.041. These same subtypes (18C and 23F also demonstrated change scores from baseline which were significant, in favor of the arabinogalactan group, at Day 51 (p = 0.033 and 0.001 and at Day 72 (p = 0.012 and p = 0.003. Change scores from baseline and mean values were greater in the arabinogalactan group than placebo for most time points in antibody subtypes 4, 6B, 9V, and 19F, but these differences did not reach statistical significance.

    Familial Mediterranean fever (FMF) is refractory to colchicine prophylaxis in 10-20% of patients. In a number of patient series, treatment with anakinra, an interleukin-1-blocking agent, prevented FMF attacks in those with colchicine-resistant FMF. This study was undertaken to evaluate the efficacy and safety of anakinra in the treatment of colchicine-resistant FMF, using a randomized controlled trial. Patients with colchicine-resistant FMF receiving colchicine (dosage ≥1.5 to ≤3 mg/day) were recruited and randomly assigned to receive anakinra or placebo (vehicle). The treatment duration was 4 months. Primary efficacy outcomes were the number of attacks per month, and the number of patients with a mean of FMF (14 women) were enrolled, of whom 12 were randomized to receive anakinra and 13 to receive placebo. The mean ± SD number of attacks per patient per month was 1.7 ± 1.7 in those receiving anakinra and 3.5 ± 1.9 in those receiving placebo (P = 0.037). Six patients in the anakinra group, compared to none in the placebo group, had treatment for colchicine-resistant FMF. © 2016, American College of Rheumatology.

    Constipation has a significant impact on quality of life. Aim of this study was to evaluate the safety and the efficacy for relieving dyschezia symptoms of a CO2-releasing suppository in a randomized, placebo-controlled, clinical trial. Fifty-three office-based primary care physicians and 24 gastroenterologists conducted the study in France, between November 2010 and January 2012. Patients (aged 18-75 years) with dyschezia were eligible. Patients were randomly allocated a once-a-day suppository (CO2-releasing suppository or placebo) for 21 days. Primary endpoint was the change, from Day 0 to Day 21, in the intensity of discomfort related to dyschezia based on a self-assessed 0-100 visual analogue scale. A total of 323 patients were randomized, i.e. 166 into the intervention group and 157 into the placebo group. Co-variance analysis showed a greater reduction in discomfort visual analogue scale score in the intervention group (-34.5mm; standard error of the mean: 1.8mm) than in the placebo group (-26.2mm; standard error of the mean: 1.9 mm; psuppository was confirmed for all secondary efficacy parameters. No significant side effects for either treatment were observed. A CO2-releasing suppository is more effective than a placebo for the relief of symptoms of dyschezia. This efficacy is associated with a good safety profile. Copyright © 2014 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd. All rights reserved.

    Purpose: To investigate whether magnesium oxide during external-beam radiotherapy for prostate cancer reduces intrafraction prostate motion in a double-blind, placebo-controlled randomized trial. Methods and Materials: At the Department of Radiotherapy, prostate cancer patients scheduled for intensity-modulated radiotherapy (77 Gy in 35 fractions) using fiducial marker-based position verification were randomly assigned to receive magnesium oxide (500 mg twice a day) or placebo during radiotherapy. The primary outcome was the proportion of patients with clinically relevant intrafraction prostate motion, defined as the proportion of patients who demonstrated in {>=}50% of the fractions an intrafraction motion outside a range of 2 mm. Secondary outcome measures included quality of life and acute toxicity. Results: In total, 46 patients per treatment arm were enrolled. The primary endpoint did not show a statistically significant difference between the treatment arms with a percentage of patients with clinically relevant intrafraction motion of 83% in the magnesium oxide arm as compared with 80% in the placebo arm (p = 1.00). Concerning the secondary endpoints, exploratory analyses demonstrated a trend towards worsened quality of life and slightly more toxicity in the magnesium oxide arm than in the placebo arm; however, these differences were not statistically significant. Conclusions: Magnesium oxide is not effective in reducing the intrafraction prostate motion during external-beam radiotherapy, and therefore there is no indication to use it in clinical practice for this purpose.

    The current work assessed a pharmaceutical dosage form of Myrtus communis L. (myrtle) in reflux disease compared with omeprazol via a 6-week double-blind randomized controlled clinical trial. Forty-five participants were assigned randomly to 3 groups as A (myrtle berries freeze-dried aqueous extract, 1000 mg/d), B (omeprazol capsules, 20 mg/d), and C (A and B). The assessment at the beginning and the end of the study was done by using a standardized questionnaire of frequency scale for the symptoms of gastroesophageal reflux disease (FSSG). In all groups, both reflux and dyspeptic scores significantly decreased in comparison with the respective baselines. Concerning each group, significant changes were found in FSSG, dysmotility-like symptoms and acid reflux related scores. No significant differences were observed between all groups in final FSSG total scores (FSSG2). Further studies with more precise design and larger sample size may lead to a better outcome to suggest the preparation as an alternative intervention.

    We developed and evaluated the effect of Multimodal Cognitive Enhancement Therapy (MCET) consisting of cognitive training, cognitive stimulations, reality orientation, physical therapy, reminiscence therapy, and music therapy in combination in older people with mild cognitive impairment (MCI) or mild dementia. This study was a multi-center, double-blind, randomized, placebo-controlled, two-period cross-over study (two 8-week treatment phases separated by a 4-week wash-out period). Sixty-four participants with MCI or dementia whose Clinical Dementia Rating was 0.5 or 1 were randomized to the MCET group or the mock-therapy (placebo) group. Outcomes were measured at baseline, week 9, and week 21. Fifty-five patients completed the study. Mini-Mental State Examination (effect size = 0.47, p = 0.013) and Alzheimer's Disease Assessment Scale-Cognitive Subscale (effect size = 0.35, p = 0.045) scores were significantly improved in the MCET compared with mock-therapy group. Revised Memory and Behavior Problems Checklist frequency (effect size = 0.38, p = 0.046) and self-rated Quality of Life - Alzheimer's Disease (effect size = 0.39, p = 0.047) scores were significantly improved in the MCET compared with mock-therapy. MCET improved cognition, behavior, and quality of life in people with MCI or mild dementia more effectively than conventional cognitive enhancing activities did.

    The aim of this randomized double-blind placebo-controlled study was to investigate the effect of low-level laser therapy (LLLT) on markers of muscle damage (creatine kinase (CK) and strength performance) in the biceps brachii. Twenty-two physically active men were randomized into two groups: placebo and laser. All volunteers were submitted to an exercise-induced muscle damage protocol for biceps brachii (biceps curl, 10 sets of 10 repetitions with load of 50% of one-repetition maximum test (1RM)). Active LLLT (808 nm; 100 mW; 35.7 W/cm(2), 357.14 J/cm(2) per point, energy of 1 J per point applied for 10 s on four points of the biceps brachii belly of each arm) or placebo was applied between the sets of the biceps curl exercise. CK activity and maximum strength performance (1RM) were measured before, immediately after, 24, 48, and 72 h after the exercise-induced muscle damage protocol. There was an increase in CK activity after the muscle damage protocol in both groups; however, this increase was attenuated in the laser group compared to the placebo group at 72 h (placebo = 841 vs. laser = 357%; p effect on the recovery of strength performance.

    Full Text Available Objective: To determine the efficacy of topical curcumin in reducing breast inflammation in women suffering from lactational mastitis. Methods: A randomized double-blind, placebo-controlled study including 63 breastfeeding women with lactational mastitis were randomly assigned to receive curcumin topical cream, one pump every 8 hours for 3 days (n=32 or topical moisturizer as placebo (n=31. Using an index for severity of breast inflammation, all of the patients had moderate breast inflammation before entering the study. The outcome of treatment was evaluated using the same index at 24, 48 and 72 hours of starting the treatment. Results: There was no significant difference between two study groups regarding the baseline characteristics such as age (p=0.361 and duration of lactation (p=0.551. After 72-hour of therapy, patients in curcumin groups had significantly lower rate of moderate (p=0.019 and mild (p=0.002 mastitis. Patients in curcumin group had significantly lower scores for tension (p<0.001, erythema (p<0.001 and pain (p<0.001, after 72-hour of treatment. Conclusion: The results of the current study indicate that topical preparation of curcumin successfully decrease the markers of lactational mastitis such as pain, breast tension and erythema within 72 hours of administration without side effects. Thus, topical preparation of curcumin could be safely administered for those suffering from lactational mastitis after excluding infectious etiologies.

    Bowel preparation using large volume of polyethylene glycol (PEG) solutions is often poorly tolerated. Therefore, there are ongoing efforts to develop an alternative bowel cleansing regimen that should be equally effective and better tolerated. The aim of this study was to assess the efficacy of lubiprostone (versus placebo) plus PEG as a bowel cleansing preparation for colonoscopy. Our study was a randomized, double-blind placebo-controlled design. Patients scheduled for screening colonoscopy were randomized 1:1 to lubiprostone (group 1) or placebo (group 2) plus 1 gallon of PEG. The primary endpoints were patient's tolerability and endoscopist's evaluation of the preparation quality. The secondary endpoint was to determine any reduction in the amount of PEG consumed in the lubiprostone group compared with the placebo group. One hundred twenty-three patients completed the study and were included in the analysis. There was no difference in overall cleanliness. The volume of PEG was similar in both the groups. The volume of PEG approached significance as a predictor of improved score for both the groups (P = 0.054). Lubiprostone plus PEG was similar to placebo plus PEG in colon cleansing and volume of PEG consumed. The volume of PEG consumed showed a trend toward improving the quality of the colon cleansing.

    Background An increasing number of studies are reporting that ketamine could be treated as a novel antidepressant for major depressive disorder (MDD). Therefore, we performed this meta-analysis to comprehensively and systematically assess the efficacy of ketamine for treating patients with MDD. Method Randomized, double-blind, placebo-controlled studies on ketamine versus placebo for treating MDD were searched up to April 2016 in medical databases (PubMed, CCTR, Web of Science, Embase, CBM-disc, and CNKI). Three treatment time points (24 and 72 h, and day 7) were chosen. Response and remission rates were the main outcomes. The random effects model was used. An intention-to-treat analysis was conducted. Results Nine high-quality studies that included 368 patients were selected to compare the efficacy of ketamine to placebo. The therapeutic effects of ketamine at 24 and 72 h, and day 7 were found to be significantly better than placebo. Response and remission rates in the ketamine group at 24 and 72 h, and day 7 were 52.2% and 20.6%; 47.9% and 23.8%; and 39.8% and 26.2%, respectively. No significant heterogeneity existed, and the Egger’s test showed no publication bias. Conclusion These results indicated that ketamine could yield a good efficacy in the rapid treatment of MDD. Future large-scale clinical studies are needed to confirm our results and investigate the mid- and long-term efficacy of ketamine in treating MDD. PMID:27843321

    A gluten-free diet (GFD) is currently the only available treatment for patients with celiac disease (CD). Several clinical trials have demonstrated that most celiac patients can tolerate a medium-high quantity of oats without any negative clinical effects; however, the inclusion of oats in GFD is still a matter of debate. In this study, Italian children with CD were enrolled in a 15-month, randomized, double-blind, placebo-controlled multicenter trial. Participants were randomized in two groups following either A-B treatment (6 months of diet “A”, 3 months of standard GFD, 6 months of diet “B”), or B-A treatment (6 months of diet “B”, 3 months of standard GFD, 6 months of diet “A”). A and B diets included gluten-free (GF) products (flour, pasta, biscuits, cakes and crisp toasts) with either purified oats or placebo. Clinical data (Gastrointestinal Symptoms Rate Scale [GSRS] score) and intestinal permeability tests (IPT), were measured through the study period. Although the study is still blinded, no significant differences were found in GSRS score or the urinary lactulose/mannitol (L/M) ratio between the two groups after 6 months of treatment. These preliminary results suggest that the addition of non-contaminated oats from selected varieties in the treatment of children with CD does not determine changes in intestinal permeability and gastrointestinal symptoms.

    Several studies have shown that a large number of patients who are fulfilling the criteria for irritable bowel syndrome (IBS) are sensitive to gluten. The aim of this study was to evaluate the effect of a gluten-free diet on gastrointestinal symptoms in patients with IBS. In this double-blind randomized, placebo-controlled trial, 148 IBS patients fulfilling the Rome III criteria were enrolled between 2011 and 2013. However, only 72 out of the 148 commenced on a gluten-free diet for up to six weeks and completed the study; clinical symptoms were recorded biweekly using a standard visual analogue scale (VAS). In the second stage after six weeks, patients whose symptoms improved to an acceptable level were randomly divided into two groups; patients either received packages containing powdered gluten (35 cases) or patients received placebo (gluten free powder) (37 cases). Overall, the symptomatic improvement was statistically different in the gluten-containing group compared with placebo group in 9 (25.7%), and 31 (83.8%) patients respectively (p gluten. Using the term of IBS can therefore be misleading and may deviate and postpone the application of an effective and well-targeted treatment strategy in gluten sensitive patients.

We set up a double-blind, randomized placebo-controlled trial to investigate the effects of testosterone supplementation on functional mobility, quality of life, body composition, cognitive function, vascular function and risk factors, and bone mineral density in older hypogonadal men. We recruited 237 men with serum testosterone levels below 13.7 nmol/L and ages 60–80 years. They were randomized to either four capsules of 40 mg testosterone undecanoate (TU or placebo daily for 26 weeks. Primary endpoints are functional mobility and quality of life. Secondary endpoints are body composition, cognitive function, aortic stiffness and cardiovascular risk factors and bone mineral density. Effects on prostate, liver and hematological parameters will be studied with respect to safety. Measure of effect will be the difference in change from baseline visit to final visit between TU and placebo. We will study whether the effect of TU differs across subgroups of baseline waist girth ( At baseline, mean age, BMI and testosterone levels were 67 years, 27 kg/m2 and 10.72 nmol/L, respectively.

    Background According to Iranian traditional medicine, using safe ginger may contribute to taking less chemical medicines and result in fewer side effects. Objective To determine the influence of using ginger before operation on nausea and vomiting, after cataract surgery under general anesthesia. Methods This study was a double-blind placebo-controlled randomized clinical trial conducted at Kurdistan University of Medical Sciences in 2015. 122 candidates of cataract surgery were randomly allocated in three groups. The first group received a ginger capsule in a single 1 g dose, the second received two separate doses of ginger capsule each containing 500 mg and the third group received placebo capsule before operation. The patients were examined and studied for the level of nausea and occurrence of vomiting for 6 hours after the operation. The intensity of nausea was scored from zero to ten, based upon Visual Analog Scale. SPSS version 20 was used to analyze the data. We used Chi square and Kruskal-Wallis test for the analyses of outcomes. Results The frequency and intensity of nausea and the frequency of vomiting after operation among those who had taken the ginger capsule in 2 separate 500 mg doses was less than the other 2 groups. This difference was significant (pKurdistan University of Medical Sciences, Sanandaj, Iran. PMID:28243400

    Muscle damage induced by an acute bout of eccentric exercise results in transient arterial stiffening. In this study, we sought to determine the effects of progressive eccentric resistance exercise training on vascular functions, and whether herb supplementation would enhance training adaptation by ameliorating the arterial stiffening effects. By using a double-blinded randomized placebo-controlled design, older adults were randomly assigned to either the Panax ginseng and Salvia miltiorrhiza supplementation group (N=12) or the placebo group (N=11). After pre-training testing, all subjects underwent 12 weeks of unilateral eccentric-only exercise training on knee extensor. Maximal leg strength and muscle quality increased in both groups (PEccentric exercise training did not elicit any significant changes in muscle damage, oxidative and inflammatory biomarkers. There were no significant changes in blood pressure or endothelium-dependent vasodilation. None of the measures of arterial stiffness changed significantly with eccentric resistance training in both groups. These results suggest that Chinese herb supplementation does not appear to modulate vascular, and inflammatory adaptations to eccentric exercise training in middle-aged and older adults. However, Chinese herb supplementation abolished the increase in muscle mass induced by eccentric resistance training. (Trial registration: ClinicalTrials.gov: NCT02007304. Registered Dec. 5, 2013).

    Full Text Available Several studies have shown that a large number of patients who are fulfilling the criteria for irritable bowel syndrome (IBS are sensitive to gluten. The aim of this study was to evaluate the effect of a gluten-free diet on gastrointestinal symptoms in patients with IBS. In this double-blind randomized, placebo-controlled trial, 148 IBS patients fulfilling the Rome III criteria were enrolled between 2011 and 2013. However, only 72 out of the 148 commenced on a gluten-free diet for up to six weeks and completed the study; clinical symptoms were recorded biweekly using a standard visual analogue scale (VAS. In the second stage after six weeks, patients whose symptoms improved to an acceptable level were randomly divided into two groups; patients either received packages containing powdered gluten (35 cases or patients received placebo (gluten free powder (37 cases. Overall, the symptomatic improvement was statistically different in the gluten-containing group compared with placebo group in 9 (25.7%, and 31 (83.8% patients respectively (p < 0.001. A large number of patients labelled as irritable bowel syndrome are sensitive to gluten. Using the term of IBS can therefore be misleading and may deviate and postpone the application of an effective and well-targeted treatment strategy in gluten sensitive patients.

    Our recent pilot study showed better outcomes using a combination of low-dose cyclosporine and glucosamine than cyclosporine alone in the treatment of atopic dermatitis (AD). Here, a randomized, placebo-controlled, double-blind, parallel-designed study was planned to compare the efficacy and safety of low-dose cyclosporine and glucosamine combination to low-dose cyclosporine alone for the treatment of patients with moderate to severe AD. AD patients with a Severity Scoring of Atopic Dermatitis (SCORAD) index ≥ 30 were randomly assigned in a 1:1 ratio to receive either cyclosporine 2 mg/kg and glucosamine 25 mg/kg (group A) or cyclosporine and placebo (group B) for 8 weeks. SCORAD indices, serum levels of chemokine ligand 17 and interleukin-31, eosinophil counts, and blood cyclosporine levels were examined before and after treatment. The SCORAD indices for group A (n = 19) were significantly reduced after the treatment and a significant correlation between the changes in the SCORAD indices and changes in the serum levels of chemokine ligand 17, but not interleukin-31, was detected. Glucosamine combined with cyclosporine did not increase adverse events and serum cyclosporine levels compared with cyclosporine alone. Therefore, combination of low-dose cyclosporine and glucosamine may be useful to allow the long-term use of cyclosporine in the treatment of patients with moderate to severe AD.

    The objective of this study was to test the hypothesis that dry needling is more effective than sham dry needling in the treatment of myofascial pain syndrome (MPS). This was a prospective, double-blinded, randomized-controlled study conducted in an outpatient clinic. Thirty-nine subjects with established myofascial trigger points were randomized into two groups: study group (N = 22) and placebo group (N = 17). Dry needling was applied using acupuncture needles, and sham dry needling was applied in the placebo group. The treatment was composed of six sessions which were performed in 4 weeks; the first four sessions were performed twice a week (for 2 weeks) and the last two, once a week (for 2 weeks). The visual analog scale (VAS) and Short Form-36 (SF-36) were used. When compared with the initial values, VAS scores of the dry needling group following the first and sixth sessions were significantly lower (p = 0.000 and p dry needling group (p = 0.034 and p dry needling group, whereas only those of vitality scores were found to be increased significantly in the placebo (sham needling) group. The present study shows that the dry needling treatment is effective in relieving the pain and in improving the quality of life of patients with MPS.

    Aim: To conduct a double-blind, placebo-controlled randomized and dose-ranging study to evaluate the safety and efficacy of the extract of Ganoderma lucidum (G. lucidum) in men with lower urinary tract symptoms (LUTS). Methods: We enrolled male volunteers (> 50 years) with an International Prostate Symptom Score (IPSS; questions 1-7)≥ 5 and a prostate-specific antigen (PSA) value < 4 ng/mL. Volunteers were randomized into groups of placebo (n = 12), G. lucidum of 0.6 mg (n = 12), 6 mg (n = 12) or 60 mg (n = 14), administered once daily. Efficacy was measured as a change from baseline in IPSS and the peak urine flow rate (Qmax). Prostate volume and residual urine were estimated by ultrasonography, and blood tests, including PSA levels, were measured at baseline and at the end of the treatment. Results: The overall administration was well tolerated, with no major adverse effects. Statistical significances in the magnitude of changes between the experimental groups were observed at weeks 4 and 8. No changes were observed with respect to Qmax, residual urine, prostate volume or PSA levels. Conclusion: The extract of G. lucidum was well tolerated and an improvement in IPSS was observed. The recommended dose of the extract of G. lucidum is 6 mg in men with LUTS. (Asian J Androl 2008 Jul; 10: 651-658)

    At present, it is unclear what the role is of laparoscopic ovarian diathermy (LOD) and of metformin administration as second-line treatments for ovulation induction in women with polycystic ovary syndrome (PCOS) after failure of clomiphene citrate (CC) treatment. The aim of the present study was to compare in a randomized double-blind placebo-controlled fashion the effectiveness of LOD with metformin administration in the treatment of CC-resistant women with PCOS. A total of 120 overweight primary infertile anovulatory CC-resistant women with PCOS were enrolled and randomized into two groups of treatment. Group A underwent diagnostic laparoscopy, whereas group B underwent LOD. At hospital discharge, the patients were treated for 6 months with metformin cloridrate (group A; 850 mg twice daily) or with multivitamins (group B). The ovulation, pregnancy, abortion, and live-birth rates were evaluated. At the end of the study, the total ovulation rate was not statistically different between both treatment groups (54.8 vs. 53.2% [correction] in groups A and B, respectively), whereas the pregnancy (21.8 [correction] vs. 13.4%), the abortion (9.3 [correction] vs. 29.0%), and the live-birth (86.0 [correction] vs. 64.5%) rates were significantly (P < 0.05) different between the two groups. Our data show that metformin administration is more effective than LOD in overall reproductive outcomes in overweight infertile CC-resistant women with PCOS.

    To evaluate the efficacy, safety, and tolerability of risperidone monotherapy for the treatment of an acute mixed or manic episode in children and adolescents with bipolar I disorder. This randomized, placebo-controlled, double-blind, 3-arm study (N = 169) included children and adolescents (ages 10-17 years) with a DSM-IV diagnosis of bipolar I disorder, experiencing a manic or mixed episode. Study participants were randomized to placebo (n = 58), risperidone 0.5-2.5 mg/day (n = 50), or risperidone 3-6 mg/day (n = 61) for 3 weeks. The primary efficacy measure was change in Young Mania Rating Scale (YMRS) total score from baseline to end point. Safety assessments included adverse event (AE) monitoring and scores on extrapyramidal symptom rating scales. Improvement in mean YMRS total score was significantly greater in risperidone-treated subjects than in placebo-treated subjects [mean change (SD) -9.1 (11.0) for placebo; -18.5 (9.7) for risperidone 0.5-2.5 mg (p children and adolescents experiencing acute manic or mixed episodes of bipolar I disorder. Results indicate that risperidone 0.5-2.5 mg has a better benefit-risk profile than risperidone 3-6 mg.

    Full Text Available Background: Quercetin, a phenolic compound, exhibits various functional effectsthat includeanti-oxidant, anti-dyslipidemic, and anti-dysglycemic activities, in addition tobeneficial effects on cognitive function. We evaluated the effects of a powder made from quercetin-rich onions (‘Quergold’ and ‘Sarasara-gold’ on cognitive function.Methods:In this randomized, double-blind, placebo-controlled study, we randomized 50 adults (25 males and 25 females, aged 65–84 years and made them consume products made from quercetin-rich (active test food group or quercetin-free(placebo food group onions. Cognitive function,hematological, and biological examinations were performed at the beginning (week 0 of the study and at weeks 12 and 24 after the start of the study. Results:There were no differences in the Mini-Mental State Examination (MMSE and cognitive impairment rating scale scores between the two groups. However, in younger subjects, the MMSE scores were significantly higher in the active test food group than in the placebo food group at week 24 (p = 0.019. Conclusion: These results suggest that the ingestion of quercetin-rich onions improves cognitive function and reduce cognitive declinein elderly people.

    Antithrombotic drugs, such as low-dose aspirin (LDA) and clopidogrel, can cause upper gastrointestinal complications. The goal of the present study was to investigate whether a mucosal-protective agent, rebamipide, could prevent gastric mucosal injuries induced by LDA with or without clopidogrel in healthy subjects. A randomized, double-blind, placebo-controlled trial was performed with 32 healthy male volunteers. Subjects were randomly assigned to a 14-day course of one of the following regimens: group A, placebo (tid) + LDA; group B, rebamipide (100 mg tid) + LDA (100 mg once-daily); group C, placebo + LDA + clopidogrel (75 mg once-daily); or group D, rebamipide + LDA + clopidogrel. The grade of gastric mucosal injuries was evaluated by esophagogastroduodenoscopy before and after dosing (on day 0 and day 14), and the grade of gastric mucosal injury was assessed according to the modified Lanza score. Subjective symptoms were assessed using the Gastrointestinal Symptom Rating Scale (GSRS). A rapid urease test was performed on day 0, and blood tests were performed on day 0 and day 14. Rebamipide significantly inhibited gastric mucosal injury induced by LDA alone or by LDA plus clopidogrel when compared with placebo in healthy subjects. GSRS score and hemoglobin level were not significantly different among the four groups. Rebamipide is useful for the primary prevention of gastric mucosal injury induced by LDA alone or by LDA plus clopidogrel in healthy subjects.

    Full Text Available Methadone maintenance therapy is an effective treatment for opiate dependence, but more than three-quarters of persons receiving the treatment report sleep quality disturbances. In this double-blind, randomized, controlled trial, we recruited 90 individuals receiving methadone for at least one month who reported sleep disturbances and had Pittsburgh Sleep Quality Index (PSQI scores > 5. The purpose of this study was to determine whether Suan Zao Ren Tang, one of the most commonly prescribed traditional Chinese medications for treatment of insomnia, improves subjective sleep among methadone-maintained persons with disturbed sleep quality. Ninety patients were randomly assigned to intervention group (n=45 and placebo group (n=45, and all participants were analyzed. Compared with placebo treatment, Suan Zao Ren Tang treatment for four weeks produced a statistically significant improvement in the mean total PSQI scores (P=0.007 and average sleep efficiency (P=0.017. All adverse events (e.g., lethargy, diarrhea, and dizziness were mild in severity. Suan Zao Ren Tang is effective for improving sleep quality and sleep efficiency among methadone-maintained patients with sleep complaints.

    Persistent proteinuria is an important factor contributing to the progression of diabetic nephropathy. The present randomized double-blind placebo-controlled multicenter clinical study evaluated the efficacy and safety of telmisartan combined with the antioxidant probucol in reducing urinary protein levels in patients with type 2 diabetes (T2D). Patients with T2D and 24-h proteinuria 0.5-3 g were enrolled in the study and randomly assigned to one of two groups: a telmisartan or a probucol + telmisartan group. Both groups were given telmisartan 80 mg q.d. for 48 weeks. The probucol + telmisartan group was given probucol 500 mg b.i.d. for the first 24 weeks, with the dosage then reduced to 250 mg b.i.d. for the remaining 24 weeks. The telmisartan group was given probucol placebo. In all, 160 patients were enrolled in the present study. The 24-h proteinuria levels were significantly reduced in the probucol + telmisartan compared with telmisartan group. For patients with baseline 24-h proteinuria levels telmisartan group. There was no significant difference between the two groups for either adverse cardiovascular or other events. In patients with diabetic nephropathy, probucol combined with telmisartan more effectively reduces urinary protein levels than telmisartan alone. © 2015 The Authors.

    The current study was conducted to evaluate the effects of zinc supplementation on endocrine outcomes, biomarkers of inflammation, and oxidative stress in patients with polycystic ovary syndrome (PCOS). This study was a randomized double-blind, placebo-controlled trial. Forty-eight women (18-40 years) with PCOS diagnosed according to Rotterdam criteria were randomly assigned to receive either 220 mg zinc sulfate (containing 50 mg zinc) (group 1; n = 24) and/or placebo (group 2; n = 24) for 8 weeks. Hormonal profiles, biomarkers of inflammation, and oxidative stress were measured at study baseline and after 8-week intervention. After 8 weeks of intervention, alopecia (41.7 vs. 12.5%, P = 0.02) decreased compared with the placebo. Additionally, patients who received zinc supplements had significantly decreased hirsutism (modified Ferriman-Gallwey scores) (-1.71 ± 0.99 vs. -0.29 ± 0.95, P zinc intake on reducing high-sensitivity C-reactive protein (hs-CRP) levels (P = 0.06) was also observed. We did observe no significant changes of zinc supplementation on hormonal profiles, inflammatory cytokines, and other biomarkers of oxidative stress. In conclusion, using 50 mg/day elemental zinc for 8 weeks among PCOS women had beneficial effects on alopecia, hirsutism, and plasma MDA levels; however, it did not affect hormonal profiles, inflammatory cytokines, and other biomarkers of oxidative stress.

    A gluten-free diet (GFD) is currently the only available treatment for patients with celiac disease (CD). Several clinical trials have demonstrated that most celiac patients can tolerate a medium-high quantity of oats without any negative clinical effects; however, the inclusion of oats in GFD is still a matter of debate. In this study, Italian children with CD were enrolled in a 15-month, randomized, double-blind, placebo-controlled multicenter trial. Participants were randomized in two groups following either A-B treatment (6 months of diet "A", 3 months of standard GFD, 6 months of diet "B"), or B-A treatment (6 months of diet "B", 3 months of standard GFD, 6 months of diet "A"). A and B diets included gluten-free (GF) products (flour, pasta, biscuits, cakes and crisp toasts) with either purified oats or placebo. Clinical data (Gastrointestinal Symptoms Rate Scale [GSRS] score) and intestinal permeability tests (IPT), were measured through the study period. Although the study is still blinded, no significant differences were found in GSRS score or the urinary lactulose/mannitol (L/M) ratio between the two groups after 6 months of treatment. These preliminary results suggest that the addition of non-contaminated oats from selected varieties in the treatment of children with CD does not determine changes in intestinal permeability and gastrointestinal symptoms.

    'Recurrent brief depression' (RBD) is a common, distressing and impairing depressive disorder for which there is no current proven pharmacological or psychological treatment. This multicentre, randomized, fixed-dose, parallel-group, placebo-controlled study of the reversible inhibitor of monoamine oxidase moclobemide (450 mg/day) and the tricyclic antidepressant imipramine (150 mg/day) evaluated the potential efficacy of active medication, when compared with placebo, in patients with recurrent brief depression, recruited in the mid-1990s. After a 2-4-week single-blind placebo run-in period, a total of 35 patients were randomized to receive double-blind medication for 4 months, but only 16 completed the active treatment period. An intention-to-treat analysis of the 34 evaluable patients found no evidence for the efficacy of moclobemide or imipramine, when compared with placebo, in significantly reducing the severity, duration or frequency of depressive episodes. A total of 28 patients experienced at least one adverse event, and four patients engaged in nonfatal self-harm. Limitations of the study include the small sample size and the high rate of participant withdrawal. The lack of efficacy of these antidepressant drugs and the previous finding of the lack of efficacy of the selective serotonin reuptake inhibitor fluoxetine together indicate that medications other than antidepressant drugs should be investigated as potential treatments for what remains a common, distressing and potentially hazardous condition.

    The aim of this randomized, double-blind, controlled study was to evaluate the antidandruff activity exerted by a new shampoo on patients affected by dandruff and/or mild seborrheic dermatitis by means of both D-squame technique coupled with image analysis and clinical assessments. Thirty-four patients were enrolled and 1:1 randomly assigned to either a test shampoo or a comparative shampoo group. Treatment schedule was twice a week for 4 weeks. The D-squame technique was shown to be able to objectively record variations in scalp desquamation both between test and comparative groups and within the same group over time. The results obtained with this instrumental approach showed a statistically significant reduction by 52% vs baseline after 2 weeks of treatment. There was an even greater reduction after 4 weeks (-66%). This reduction was statistically significant compared with the comparative group at the same time points. The analysis of all the other parameters (except Wood's lamp) confirmed the superiority of the test vs the comparative shampoo. The test shampoo proved to be safe, well tolerated, and accepted by the patients for cosmetic acceptability and efficacy. The study confirmed the antidandruff efficacy of the test shampoo and its superiority vs the comparative shampoo.

    The aim of this study was to evaluate the analgesic effects of low-level laser therapy (LLLT) on preinjection sites in patients scheduled for third molar removal. This double-blind randomized controlled trial included 163 healthy patients undergoing third molar extractions. The study participants were randomly divided into an LLLT and a placebo group. Objective and subjective data sets were obtained from physiologic feedback (heart rate and sweat response) and a questionnaire, respectively. In the LLLT group, each targeted injection site was irradiated twice with 198 mW continuous wave for 30 seconds with a 0.088 cm(2) focal spot at an applied energy of 5.94 J and fluence of 67.50 J/cm(2). Measurements were recorded from 4 time-points during data acquisition. There was no significant difference between the LLLT and placebo groups in pain experience scores associated with the injected sites for maxillary or mandibular third molar extractions. Mean heart rates before and during injection were lower in the LLLT group than in the placebo group for both maxillary and mandibular regions. No statistically significant differences were observed for any remaining parameters. The present data indicated that preinjection LLLT did not effectively decrease the pain felt during local anesthetic injections before third molar surgery. Copyright © 2017 Elsevier Inc.

    Dermatologic toxicities resulting in dose reduction or discontinuation of treatment pose challenges for targeted anticancer therapies. We conducted this randomized, double-blind, placebo-controlled trial to investigate the efficacy of topical application of Compound Danxiong Granules (CDG) for treatment of dermatologic toxicities associated with targeted anticancer therapies. One hundred and ten patients with dermatologic toxicities induced by targeted anticancer therapies were randomly assigned to CDG or placebo group. Each crude herb (Rhizoma Chuanxiong, Paeonia suffruticosa Andr., Cortex Phellodendri, Geranium sibiricum L., and Flos Carthami) was prepared as an instant herbal powder. Application of the CDG via topical washes lasted 20 minutes, twice daily, for 10 days. The primary outcome was the total effective rate, defined as reduction in at least one grade of skin toxicity. The total effective rate was 77.61% (52/67) in the CDG group and 27.27% (9/33) in the placebo group (P dermatologic toxicities induced by targeted anticancer therapies. The effect of CDG was more pronounced in hand-foot skin reaction.

    Full Text Available Objectives. Many patients with bipolar disorder suffer from metabolic disorder. Lovastatin is effective for treating major depression. This double-blind randomized placebo controlled clinical trial investigates whether lovastatin is a useful adjuvant to lithium for treating mania. Methods. Fifty-four patients with bipolar disorder-manic phase were randomly allocated into lovastatin or placebo group. The clinical symptoms were assessed at baseline, week 2, and week 4 using Young Mania Rating Scale. Adverse effects were checked. Results. Forty-six out of 54 patients completed this trial. The mania score in the lovastatin group decreased from 40.6 (11.1 at baseline to 12.9 (8.7 and 4.1 (5.4 at weeks 2 and 4, respectively. The score in the placebo group decreased from 41.0 (11.2 at baseline to 12.8 (8.07 and 5.8 (4.6 at weeks 2 and 4, respectively. However, there was no significant difference between groups at week 2 and week 4. The adverse effects rates were comparable between the two groups. No serious adverse effect was found. Tremor and nausea were the most common adverse effects. Conclusions. Lovastatin neither exacerbated nor decreased the symptoms of mania in patients with bipolar disorder. Current results support that the combination of lovastatin with lithium is tolerated well in bipolar disorder. The trial was registered with the Iranian Clinical Trials Registry (IRCT201302203930N18.

    Among several beneficial cardiovascular actions of statins, experimental studies have suggested that statins may also induce a mild blood pressure (BP) reduction. However, clinical data were controversial and the potential hypotensive statin effect remains uncertain. This study aimed to investigate the effect of atorvastatin on ambulatory BP in patients with mild hypertension and hypercholesterolaemia. A total of 50 patients with mild hypertension and hypercholesterolaemia participated in this double-blind, randomized, placebo-controlled study. Patients were randomized to either 10 mg atorvastatin or placebo for 26 weeks. Background antihypertensive treatment, if any, remained unchanged during follow-up. At baseline and study-end (26 weeks), ambulatory BP monitoring and blood sampling for determination of standard biochemical and safety parameters were performed in all participants. BP loads were defined as the percentage of BP measurements exceeding the hypertension threshold of 140/90 mm Hg for daytime and 125/75 mm Hg nighttime period. Atorvastatin significantly reduced 24-h systolic and diastolic BP (DBP; median (range)) as compared with placebo (-5.0 (-21.0, 4.0) vs +1.0 (-6.0, 7.0) mm Hg, Phypercholesterolaemia. This beneficial effect of atorvastatin on BP may represent another pathway through which this drug class provides cardiovascular risk reduction.

    Full Text Available A gluten-free diet (GFD is currently the only available treatment for patients with celiac disease (CD. Several clinical trials have demonstrated that most celiac patients can tolerate a medium-high quantity of oats without any negative clinical effects; however, the inclusion of oats in GFD is still a matter of debate. In this study, Italian children with CD were enrolled in a 15-month, randomized, double-blind, placebo-controlled multicenter trial. Participants were randomized in two groups following either A-B treatment (6 months of diet “A”, 3 months of standard GFD, 6 months of diet “B”, or B-A treatment (6 months of diet “B”, 3 months of standard GFD, 6 months of diet “A”. A and B diets included gluten-free (GF products (flour, pasta, biscuits, cakes and crisp toasts with either purified oats or placebo. Clinical data (Gastrointestinal Symptoms Rate Scale [GSRS] score and intestinal permeability tests (IPT, were measured through the study period. Although the study is still blinded, no significant differences were found in GSRS score or the urinary lactulose/mannitol (L/M ratio between the two groups after 6 months of treatment. These preliminary results suggest that the addition of non-contaminated oats from selected varieties in the treatment of children with CD does not determine changes in intestinal permeability and gastrointestinal symptoms.

    Full Text Available Acute headaches are responsible for a significant percentage of the case load at primary care units and emergency rooms in Brazil. Dipyrone (metamizol is easily available in these settings, being the most frequently used drug. We conducted a randomized, placebo-controlled, double-blind study to assess the effect of dipyrone in the acute treatment of episodic tension-type headache. Sixty patients were randomized to receive placebo (intravenous injection of 10 ml saline or 1 g dipyrone in 10 ml saline. We used seven parameters of analgesic evaluation. The patients receiving dipyrone showed a statistically significant improvement (P<0.05 of pain compared to placebo up to 30 min after drug administration. The therapeutic gain was 30% in 30 min and 40% in 60 min. The number of patients needed to be treated for at least one to have benefit was 3.3 in 30 min and 2.2 in 60 min. There were statistically significant reductions in the recurrence (dipyrone = 25%, placebo = 50% and use of rescue medication (dipyrone = 20%, placebo = 47.6% for the dipyrone group. Intravenous dipyrone is an effective drug for the relief of pain in tension-type headache and its use is justified in the emergency room setting.

    Full Text Available Background and aims. Standard treatment of oral lichen planus (OLP includes topical or systemic corticosteroids that have many adverse effects. A trend toward alternative natural or herbal drugs has attended recently. This study was con-ducted to evaluate the effect of quercetin in treatment of erosive-atrophic OLP. Materials and methods. Thirty patients participated in this randomized clinical trial from April 2010 to June 2010 (Trial Registration Number: NCT01375101. Patients were randomly allocated in two groups. Both groups received the standard treatment (dexamethasone mouthwash and nystatin suspension. Experimental group received oral 250 mg quercetin hydrate capsules (bid and the control group received placebo capsules. The pain and severity of the lesions were recorded at the initial visit and the follow-ups. All recorded data were analyzed with chi-square, Mann-Whitney, t-test, Wilcoxon and Friedman tests using SPSS 11.5. Results. There were no significant differences between the two groups in severity of the lesions and pain in the follow-ups.According to the Friedman test, there was a significant reduction in pain (P = 0.01 and severity indices (P = 0.00 in the case group. These differences were not observed in the control group (P = 0.26, SI; and P = 0.86, PI. No adverse effect of quercetin was reported. Conclusion. According to the results, no significant therapeutic effect can be considered for quercetin in treatment of OLP.

    Chronic stress has a negative influence on health. The aim was to determine stress reducing effects of yoghurt enriched with bioactive components as compared to normal yoghurt. High-trait anxiety individuals (n = 67) aged 18-63 years participated in a randomized, placebo-controlled, double-blinded intervention with parallel groups. They received either yoghurt enriched with alpha-lactalbumin, casein tripeptides and B vitamins (active) or isoenergetic standard yoghurt (control). To detect changes in psychological and physiological stress, State-Trait Anxiety Inventory, Profile of Mood States, salivary cortisol, inflammatory markers, blood pressure, heart rate variability (HRV) and actigraphy were monitored. We observed higher ratings of vigor (p = 0.047) and reduced feeling of inefficiency (p = 0.048) in the active group. HRV (baseline adjusted mean 49.1 ± 2.3 ms) and recovery index (106.6 ± 33.4) were higher in the active group than in controls (42.5 ± 2.2 ms and 80.0 ± 29.3) (p = 0.046 and p = 0.02, respectively). In conclusion, daily intake of yoghurt enriched with bioactive components may aid in stress coping.

    Previous studies suggest that oral calcium supply reduces blood pressure in patients with mild to moderate hypertension. The aim of this study was to determine whether oral calcium supply reduces blood pressure in patients undergoing haemodialysis. The study was randomized, double-blind, and placebo controlled. Eleven patients received two grams of calcium per day and 12 patients received placebo. Three patients (one from the calcium group and two from the placebo group) dropped out within the first month. The groups were comparable at inclusion regarding blood pressure, weight, and serum values. Blood pressure measurements were auscultatory with a mercury manometer and diastolic blood pressure was measured as Korotkoff phase V. At inclusion a significant positive correlation between serum phosphate and blood pressure was found. After a study period of six months a significant reduction in diastolic blood pressure was found between the two groups (p < 0.05), but no difference was found in systolic blood pressure. The reduction in diastolic blood pressure was 6.9 mmHg of the pretreatment level in the calcium group. In conclusion, the treatment of secondary hyperparathyroidism with oral calcium gives good benefits in the regulation of diastolic blood pressure. A well controlled phosphate homeostasis may also be of importance for the control of blood pressure in haemodialysis patients.

    Postoperative pain control after cesarean section (C/S) is important because inadequate postoperative pain control can result in a prolonged hospital stay. In this study, we compared postoperative somatic wound pain control between patients receiving tramadol and bupivacaine, infiltrated at the wound site. In this randomized clinical trial, 98 patients, eligible for elective C/S under general anesthesia, were randomly allocated to 2 groups. Before wound closure, 20 cc of 0.025% bupivacaine and 2 mg/kg of tramadol, diluted to 20 cc, were infiltrated at the wound site in groups A and B, respectively. After surgery, the pain score was measured using the visual analogue scale (VAS). Additionally, 24-hour total morphine consumption, nausea and vomiting, and respiratory depression were compared after 2, 4, 8, 16, and 24 hours between the 2 groups. The data were analyzed using SPSS with the Student independent t test, χ(2) test, Fisher exact test, and repeated measure test. Postoperatively, there was no significant difference between these 2 groups in their VAS scores until 16 hours (P>0.05). However, at the 16(th) and 24(th) hours, the mean VAS scores were 3.20±2.24 and 2.51±2.55 in the bupivacaine group and 2.51±0.99 and 1.40±0.88 in the tramadol group, respectively (Ptramadol (2 mg/kg) at the incision site of C/S was effective in somatic wound pain relief without significant complications.

    Full Text Available Abstract Background Delayed onset muscle soreness (DOMS is muscle pain and discomfort experienced approximately one to three days after exercise. DOMS is thought to be a result of microscopic muscle fiber tears that occur more commonly after eccentric exercise rather than concentric exercise. This study sought to test the efficacy of a proprietary dietary supplement, BounceBack™, to alleviate the severity of DOMS after standardized eccentric exercise. Methods The study was a randomized, double-blind, placebo-controlled, crossover study. Ten healthy community-dwelling untrained subjects, ranging in age from 18–45 years, were enrolled. Mean differences within and between groups were assessed inferentially at each data collection time-point using t-tests for all outcome measures. Results In this controlled pilot study, intake of BounceBack™ capsules for 30 days resulted in a significant reduction in standardized measures of pain and tenderness post-eccentric exercise compared to the placebo group. There were trends towards reductions in plasma indicators of inflammation (high sensitivity C-reactive protein and muscle damage (creatine phosphokinase and myoglobin. Conclusion BounceBack™ capsules were able to significantly reduce standardized measures of pain and tenderness at several post-eccentric exercise time points in comparison to placebo. The differences in the serological markers of DOMS, while not statistically significant, appear to support the clinical findings. The product appears to have a good safety profile and further study with a larger sample size is warranted based on the current results.

    Several studies have demonstrated the effective use of dehydroepiandrosterone (DHEA) in the management of mood, however studies of its use in psychosis remain limited. The aim of this study was to investigate for the first time efficacy of DHEA augmentation with standardized antipsychotic medication (olanzapine) and to explore effects of DHEA augmentation on side-effect profiles including weight gain, glucose tolerance, aggression, quality of life and neurocognitive function. Finally, we aimed to analyze any relationship between plasma levels and clinical response to DHEA administration. Forty patients with chronic schizophrenia stabilized on olanzapine were randomized in double-blind fashion to receive either DHEA (titrated up to 150mg) or placebo augmentation for a period of 12-weeks. Blood samples were collected at baseline, mid-study and study completion. Results indicated improvement of negative symptoms (SANS scale) even when baseline scores were controlled as a covariate. Some improvement in Parkinsonism and akathisia compared to baseline was seen in patients receiving DHEA. No change in psychosis as reflected by the PANSS was noted. Patients receiving DHEA appeared to demonstrate relatively stable glucose levels compared to controls at the end of the study. An improvement in cognitive performance (most notably memory), which did not reach significance due to low sample number, was observed following DHEA administration. Results further suggest preliminary evidence of involvement of the neurosteroid system in schizophrenia pathophysiology, and confirm initial "cautious" findings identifying an agent capable of improving negative symptoms and certain features of extrapyramidal side effects.

    Background & objectives: Various inhaled corticosteroids (ICSs) are available to control the symptoms of asthma. Although beclomethasone dipropionate (BDP) and budesonide (BUD) are one of the oldest ICSs, their wide availability and low cost make them attractive options in developing countries. Due to lack of consensus on which of the two drugs is better for controlling mild persistent asthma, we undertook this study to compare the efficacy of these two drugs by measuring the change in percentage predicted forced expiratory volume in one second (FEV1) from baseline in children with mild persistent asthma. Methods: A double-blind, randomized, parallel group study was conducted in children 7-15 yr of age with newly diagnosed asthma. Of the 85 cases of mild persistent asthma, 42 received BUD while 43 received BDP at a dose of 400 µg/day using pressurized metered-dose inhaler with valved spacer for two months. The outcomes measured were change in FEV1, symptom scores and side effects. Results: There was a significant (P management of children with mild persistent asthma. [CTRI No: CTRI/2013/03/003495].

    Immunization of healthy volunteers with chloroquine ChemoProphylaxis and Sporozoites (CPS-CQ) efficiently and reproducibly induces dose-dependent and long-lasting protection against homologous Plasmodium falciparum challenge. Here, we studied whether chloroquine can be replaced by mefloquine, which is the only other licensed anti-malarial chemoprophylactic drug that does not affect pre-erythrocytic stages, exposure to which is considered essential for induction of protection by CPS immunization. In a double blind randomized controlled clinical trial, volunteers under either chloroquine prophylaxis (CPS-CQ, n = 5) or mefloquine prophylaxis (CPS-MQ, n = 10) received three sub-optimal CPS immunizations by bites from eight P. falciparum infected mosquitoes each, at monthly intervals. Four control volunteers received mefloquine prophylaxis and bites from uninfected mosquitoes. CPS-MQ immunization is safe and equally potent compared to CPS-CQ inducing protection in 7/10 (70%) versus 3/5 (60%) volunteers, respectively. Furthermore, specific antibody levels and cellular immune memory responses were comparable between both groups. We therefore conclude that mefloquine and chloroquine are equally effective in CPS-induced immune responses and protection. Trial registration: ClinicalTrials.gov NCT01422954.

    Placebo controlled double-blinded, prospectively randomized clinical trial with 17 patients (11 verum, 5 placebo) for evaluation of cellulite treatment with Acoustic Wave Therapy, (AWT(®)) was performed. The patients were treated once a week for 7 weeks, a total of 8 treatments with the D-ACTOR(®) 200 by Storz Medical AG. Data were collected at baseline, before 8th treatment, at 1 month (follow-up 1) and at 3 months (follow-up 2) after the last treatment with a patients' questionnaire, weight control, measurement of circumference and standardized photography. Treatment progress was further documented using a specially designed 3D imaging system (SkinSCAN(3D), 3D-Shape GmbH) providing an objective measure of cellulite (primary efficacy criteria). Patient's questionnaire in the verum group revealed an improvement in number and depth of dimples, skin firmness and texture, in shape and in reduction of circumference. The overall result (of skin waviness, Sq and Sz, surface and volume of depressions and elevations, Vvv and Vmp) at two follow-up visits indicates a more than medium sized superiority (MW = 0.6706) and is statistically significant (pWei-Lachin = 0.0106). The placebo group revealed no statistical significance. No side effects were seen. This indicates the efficacy and safety of AWT(®) for patients with cellulite.

    Objective To determine whether ingesting a green tea beverage enriched with catechins with a galloyl moiety during a meal reduces body fat in moderately obese adults. Design Randomized double-blind placebo-controlled study. Subjects A total of 126 obese subjects (25 ≤ body mass index tea beverages without catechins (placebo), or a group receiving green tea beverages with a low or high content of catechins with a galloyl moiety. Each subject ingested 500 mL bottled green tea beverages containing 25, 180, or 279.5 mg green tea catechins (0, 149.5, or 246.5 mg catechins with a galloyl moiety, respectively), at mealtimes for 12 weeks; the subjects were instructed to ingest the beverage during the meal that had the highest fat content on that day. Methods Anthropometric measurements and blood chemistry analysis were performed during the run-in period; at weeks 0, 4, 8, and 12 of the intake period; and at the end of the withdrawal period. Abdominal fat area was measured by computed tomography at weeks 0, 8, and 12 of the intake period and at the end of the withdrawal period. Results Both the low- and high-dose groups exhibited significant reductions in visceral and subcutaneous fat areas compared to the control group at 12 weeks post-intervention. Conclusion Ingestion of a green tea beverage enriched with catechins with a galloyl moiety during a high-fat meal reduces body fat in moderately obese adults.

    This multicenter, double-blind, placebo-controlled study examined the efficacy and safety of ipragliflozin, a sodium-glucose co-transporter 2 inhibitor, in combination with metformin in Japanese patients with type 2 diabetes mellitus (T2DM). Patients were randomized in a 2 : 1 ratio to 50 mg ipragliflozin (n = 112) or placebo (n = 56) once daily for 24 weeks, followed by a 28-week open-label extension in which all patients received 50 or 100 mg ipragliflozin, while continuing metformin. The primary outcome was the change in glycated haemoglobin (HbA1c) from baseline to week 24. HbA1c decreased significantly in the ipragliflozin group (-0.87%; adjusted mean difference from placebo: -1.30%; p < 0.001). The overall incidence of treatment-emergent adverse events was similar in both groups, although pollakiuria and constipation were more common in the ipragliflozin group; thus, ipragliflozin significantly improved glycaemic control and reduced body weight without major safety issues in Japanese patients with T2DM.

    Infrared A radiation (IRA) from solar sunlight contributes to photoaging of human skin, e.g. by upregulating MMP-1 expression in dermal fibroblasts, indicating the need for photoprotection of human skin against IRA. Up to now, however, there has been no controlled study to show that effective protection of human skin against IRA radiation is possible. Here, we have conducted a randomized, controlled, double-blinded prospective study in 30 healthy volunteers to assess the capacity of an SPF 30 sunscreen versus the same sunscreen supplemented with an antioxidant cocktail containing grape seed extract, vitamin E, ubiquinone and vitamin C to protect human skin against IRA radiation-induced MMP-1 upregulation. As expected, exposure to IRA radiation significantly upregulated MMP-1 expression, as compared to unirradiated skin, and this response was significantly reduced, if the SPF30 sunscreen plus the antioxidant cocktail had been applied prior to IRA radiation. In contrast, treatment of human skin with the SPF30 sunscreen alone did not provide significant protection. These results indicate that topically applied antioxidants effectively protect human skin against IRA radiation and that regular sunscreens need to be supplemented with specific antioxidants in order to achieve IRA photoprotection.

    Gut hormones play an important role in the adaptation of the immature neonatal gut, and their secretion may be modulated by prebiotics. Furthermore, prebiotics are well known for their hypolipidemic potentials. We tested the hypothesis that prebiotics could alter motilin and gastrin secretion and reduce lipids in healthy preterms. A total of 167 newborns were randomized to either a prebiotics enriched formula containing dietary oligosaccharides (short-chain galacto-oligo-saccharides/long-chain fructo-oligo-saccharides [scGOS/lcFOS]), at a concentration of 0.8 g/100 ml, or a common preterm formula. Day 1 and 16 basal motilin, gastrin concentrations, and lipids were evaluated together with growth parameters, gastric residue, bowel habits, and feeding tolerance. Adverse events including necrotizing enterocolitis (NEC) and septicemia were also recorded. Mean motilin increase and day 16 mean values were greater for the intervention, compared with the control group (P = .001, P = .005, respectively), while gastrin remained high in both groups. Mean cholesterol and low density lipoprotein (LDL) increase were significantly greater in the control, compared with the intervention (P = .037, and P = .001) group. Day 16 LDL levels were significantly higher in the control group. Mean weight was increased in the control group, while gastric residue was less and stool frequency was increased in the intervention group. NEC and septicemia were not statistically different between groups. A prebiotics enriched formula resulted in significant surge of motilin relating to reduced gastric residue, compared with a common preterm formula. Mean cholesterol change was lower, while LDL was not increased in the prebiotics group, compared with the control group. © 2013 American Society for Parenteral and Enteral Nutrition.

    To observe the Immune No. 2 (2) on the immune reconstitution in patients with human immunodeficiency virus or acquired immune deficiency syndrome (HIV/AIDS) after highly active antiretroviral therapy (HAART). A randomized, double-blind, placebo-controlled clinical trial was designed. 233 patients failing immune reconstitution after HAART were randomly divided into treatment group (116 cases) and control group (117 cases), respectively using Immune No. 2 plus HAART and placebo combined with HAART for 6 months. CD4, CD45RA, CD45RO cell numbers, as well as the symptoms, signs and integral improvement rates were observed in order to evaluate the immune reconstitution efficiency. after the intervention for 1 month, the effective rate of the treatment group (18.97%, 22/116) was significantly higher than that of the control group (9.40%, 11/117) (P=0.02); 3 months after treatment, the effective rate of the treatment group (27.59%, 32/116) was no difference from that of the control group (22.22%, 26/117) (P=0.31); 6 months after treatment, the effective rate of the treatment group (34.48%, 40/116) was significantly superior to the control group (21.37%, 25/117) (P=0.02). CD4, CD45RA, CD45RO count of the treatment group was significantly higher than that of the control group (P<0.05). The total score of symptoms and signs in the treatment group was significantly lowered compared with the control group (P=0.02), and the improvement of fatigue, muscle and joint pain, pruritus and shortness of breath in the treatment group was better than the control group (P<0.05). Immune No. 2 can effectively improve the numbers of CD4 cells and its subgroups, as well as the main clinical symptoms and signs of patients after HAART, thereby promoting the immune reconstitution.

    Objective To estimate the effect of progestin-only vs. combined hormonal contraceptive pills on rates of breastfeeding continuation in postpartum women. Secondary outcomes include infant growth parameters, contraceptive method continuation and patient satisfaction with breastfeeding and contraceptive method. Methods In this randomized controlled trial, postpartum breastfeeding women who desired oral contraceptives were assigned to progestin-only vs. combined hormonal contraceptive pills. At two and eight weeks postpartum, participants completed in-person questionnaires that assessed breastfeeding continuation and contraceptive use. Infant growth parameters including weight, length and head circumference were assessed at eight weeks postpartum. Telephone questionnaires assessing breastfeeding, contraceptive continuation and satisfaction were completed at 3-7 weeks and 4 and 6 months. Breastfeeding continuation was compared between groups using Cox proportional hazards regression. Differences in baseline demographic characteristics and in variables between the two intervention groups were compared using chi-square tests, Fisher’s Exact test, or two-sample t-tests as appropriate. Results Breastfeeding continuation rates, contraceptive continuation, and infant growth parameters did not differ between users of progestin-only and combined hormonal contraceptive pills. Infant formula supplementation and maternal perception of inadequate milk supply were associated with decreased rates of breastfeeding in both groups. Conclusions Choice of combined or progestin-only birth control pills administered two weeks postpartum did not adversely affect breastfeeding continuation. PMID:22143258

    Osteoarthritis is a relatively common musculoskeletal disorder that increases in prevalence with age. Worldwide, knee osteoarthritis is one of the leading causes of disability, particularly in the elderly. In numerous trials of agents for long-term pain therapy, no well-established and replicable results have been achieved. Complementary and alternative medical approaches have been employed for thousands of years to relieve knee osteoarthritis pain. Among herbal medicines, the golden plaster is the preferred and most commonlyused method in China to reduce pain in patients with knee osteoarthritis, as it causes few adverse effects. The purpose of this study will be to evaluate the efficacy and safety of golden plaster on pain in patients with knee osteoarthritis. This study will be a multicenter randomized, double-blind, placebo-controlled trial. A total of 320 participants aged 45 to 79 years with knee osteoarthritis, whose scores on a visual analog scale (VAS) are more than 20 mm,will be randomly allocated into a treatment group and a control group. A golden plaster will be administered externally to participants in the treatment group for 2 weeks, while the control group will receive a placebo plaster externally for 2 weeks. Follow-up will be at regular intervals during a 4-week period with a VAS score for pain, quality of life, and complications. This study will be a methodologically sound randomized controlled trial to assess pain relief after the intervention of golden plaster, compared to a placebo intervention in patients with knee osteoarthritis.

    Full Text Available Cephalic allodynia (CA can be observed in 50-70% of patients with chronic migraine (CM. The aim of this trial was to assess the efficacy of botulinum toxin type A (Botx-A in the treatment of CA associated with CM. In this placebo-controlled trial, patients were randomized either into Botx-A or 0.9% saline injections and efficacy measures were assessed every 4 weeks for 3 months. Efficacy endpoints were number of migraine episodes associated with CA, changes from baseline in visual analogical scale scores for pain (VAS and frequency of common analgesics use for migraine. A total of 38 subjects were randomized to saline (n=18 or Botx-A (n=20. There were no significant differences in baseline between active intervention or placebo groups regarding mean age, number of headache episodes [mean 12.1 (9.22 and 17.00 (9.69 respectively; P=0.12], pain severity as measured by the VAS or frequency of analgesic use for headache episodes. Efficacy analysis showed that Botx-A injections led to an important decrease from baseline in the mean migraine episodes associated with CA after 12 weeks (5.20 versus 11.17; P=0.01. Also, VAS scores and frequency of analgesics use for headache were significantly reduced in the Botx-A group. This study suggests that Botx-A injections are superior to saline in the treatment of CA associated with CM, with mild self limited side effects.

    Full Text Available Abstract Background Recent international guidelines recommend intra-articular corticosteroid injections for patients with hip osteoarthritis who have moderate to severe pain and do not respond satisfactorily to oral analgesic/anti-inflammatory agents. Of the five available randomized controlled trials, four showed positive effects with respect to pain reduction. However, intra-articular injection in the hip is complex because the joint is adjacent to important neurovascular structures and cannot be palpated. Therefore fluoroscopic or ultrasound guidance is needed. The systemic effect of corticosteroids has been studied in patients with impingement shoulder pain. Gluteal corticosteroid injection was almost as effective as ultrasound-guided subacromial corticosteroid injection. Such a clinically relevant effect of a systemic corticosteroid injection offers a less complex alternative for treatment of patients with hip osteoarthritis not responsive to oral pain medication. Methods/Design This is a double-blinded, randomized controlled trial. A total of 135 patients (aged > 40 years with hip osteoarthritis and persistent pain despite oral analgesics visiting a general practitioner or orthopaedic surgeon will be included. They will be randomized to a gluteal intramuscular corticosteroid injection or a gluteal intramuscular placebo (saline injection. The randomization will be stratified for setting (general practitioner and outpatient clinics of department of orthopaedics. Treatment effect will be evaluated by questionnaires at 2, 4, 6, and 12 weeks follow-up and a physical examination at 12 weeks. Primary outcome is severity of hip pain reported by the patients at 2-week follow-up. Statistical analyses will be based on the intention-to-treat principle. Discussion This study will evaluate the effectiveness of an intramuscular corticosteroid injection on pain in patients with hip osteoarthritis. Patient recruitment has started.

    2012-08-01

    Full Text Available Objectives: Transcranial direct current stimulation (tDCS has demonstrated some efficacy in treatment-resistant major depression (TRD. The majority of previous controlled studies have used anodal stimulation to the left dorsolateral prefrontal cortex (DLPFC and a control location such as the supraorbital region on for the cathode. Several open label studies have suggested effectiveness from anodal stimulation to the left DLPFC combined with cathodal stimulation to the right DLPFC. Thus, this study evaluated the efficacy of tDCS using anodal stimulation to the left DLPFC and cathodal stimulation to the right DLPFC compared to sham tDCS. Methods: Subjects between the ages of 18 and 65 were recruited from a tertiary care university hospital. Twenty-four subjects with TRD and a 17-item Hamilton Depression Rating Scale (HDRS greater than 21 were randomized to receive tDCS or sham tDCS. The rates of remission were compared between the two treatment groups.Results: The remission rates did not differ significantly between the two groups using an intention to treat analysis. More subjects in the active tDCS group had failed a course of electroconvulsive therapy in the current depressive episode. Side effects did not differ between the two groups and in general the treatment was very well tolerated. Conclusion: Anodal stimulation to the left DLPFC and cathodal stimulation to the right DLPFC was not efficacious in TRD. However, a number of methodological limitations warrant caution in generalizing from this study. Ongoing, controlled studies should provide further clarification on the efficacy of this stimulation configuration in TRD.

    In the present randomized, controlled, double-blind trial (12 wk treatment plus double-blind extension for 12 wk), 25-50 mg/d agomelatine (n = 164) and 10-20 mg/d escitalopram (n = 160) were compared for short- and long-term efficacy, subjective sleep and tolerability. The effects of these drugs on emotional experiences were also compared in patients having completed the Oxford Questionnaire on the Emotional Side-Effects of Antidepressants (agomelatine: n = 25; escitalopram: n = 20). Agomelatine and escitalopram similarly improved depressive symptoms, with clinically relevant score changes over 12 and 24 wk and notable percentage of remitters (week 12: 60.9 and 54.4%; week 24: 69.6 and 63.1% respectively). Over the 12 and 24-wk treatment periods, the 'global satisfaction on sleep' scores increased in both treatment groups and did not differ between groups. Satisfaction with sleep-wake quality was high in both groups; the 'wellness feeling on waking' was more improved with agomelatine than with escitalopram (p = 0.02). In patients with pronounced sleep complaints, quality of sleep and feeling on waking were significantly more improved with agomelatine than with escitalopram (p = 0.016 and p = 0.009, respectively). Emotional blunting was less frequent on agomelatine than on escitalopram. Indeed, 28% of patients on agomelatine vs. 60% on escitalopram felt that their emotions lacked intensity and 16% of patients on agomelatine vs. 53% on escitalopram felt that things that they cared about before illness did not seem important any more (p = 0.024). The tolerability profile of agomelatine was found to be superior to that of escitalopram and the incidence of patients with at least one emergent adverse event leading to treatment discontinuation was lower in the agomelatine group than in the escitalopram group (5.5 vs. 10.6%). The findings suggest that agomelatine displays additional long-term clinical benefits on sleep-wake quality and emotional experiences over

    This integrated analysis aimed to identify the factors associated with the most frequently re-ported treatment-emergent adverse events (TEAEs) in Asian and non-Asian patients with chronic constipation (CC) who receive prucalopride or placebo over 12 weeks. Pooled data from four randomized, double-blind, placebo-controlled, multicenter, phase III studies (NCT00488137, NCT00483886, NCT00485940, and NCT01116206) on pa-tients treated with prucalopride 2 mg or placebo were ana-lyzed. The associations between predictors and TEAEs were evaluated based on a logistic regression model. Overall, 1,821 patients (Asian, 26.1%; non-Asian, 73.9%) were analyzed. Prucalopride treatment was significantly as-sociated with diarrhea, headache, and nausea (pdiarrhea and less likely to develop abdominal pain, headache, and nausea. Prior laxative use, CC duration, and body weight were not predictive of any of these TEAEs. Con-clusions Prucalopride treatment was positively associated with diarrhea, headache, and nausea. Asian patients tended to have a higher frequency of diarrhea but lower frequencies of headache, abdominal pain, and nausea compared with non-Asians. (Gut Liver, 2015;9208-213).

    Full Text Available A randomized, double-blind, placebo-controlled study was conducted to evaluate the efficacy of GutGard, an extract of Glycyrrhiza glabra, in patients with functional dyspepsia. The primary outcome variables of the study were the change in the severity symptoms and the global assessment of efficacy. The quality of life was evaluated as a secondary outcome measure. The patients received either placebo or GutGard (75 mg twice daily for 30 days. Efficacy was evaluated in terms of change in the severity of symptoms (as measured by 7-point Likert scale, the global assessment of efficacy, and the assessment of quality of life using the short-form Nepean Dyspepsia Index. In comparison with placebo, GutGard showed a significant decrease (P≤.05 in total symptom scores on day 15 and day 30, respectively. Similarly, GutGard showed marked improvement in the global assessment of efficacy in comparison to the placebo. The GutGard group also showed a significant decrease (P≤.05 in the Nepean dyspepsia index on day 15 and 30, respectively, when compared to placebo. GutGard was generally found to be safe and well-tolerated by all patients. GutGard has shown significant efficacy in the management of functional dyspepsia.

    The aim of this study was to evaluate the cytotoxic effect of octenidine dihydrochloride/phenoxyethanol (OHP) found in vitro by conducting a randomized, double-blind controlled clinical study focusing on its safe and effective use in chronic venous leg ulcers. In total, 126 male and female patients were treated with either OHP (n = 60) or Ringer solution (n = 66). The treatment lasted over a period of maximum 12 weeks. For the assessment of the wound-healing process, clinical outcome parameters were employed, that is, time span until 100% epithelization, wound status and the wound surface area were analysed. Side effects were recorded during the study period. The median time to complete ulcer healing was comparable between the OHP and Ringer solution groups (92 versus 87 days; P = 0·952), without being influenced by wound size or duration of the target ulcer (P-values: 0·947/0·978). In patients treated with OHP, fewer adverse events (AEs) were observed compared with the Ringer group (17% versus 29% of patients reported 20 versus 38 AEs). OHP is well suitable for the treatment of chronic wounds without cytotoxic effects. Furthermore, OHP does not impair the wound healing in chronic venous ulcers. © 2011 The Authors. © 2011 Blackwell Publishing Ltd and Medicalhelplines.com Inc.

    Full Text Available Objective. To evaluate the effects of ezetimibe/simvastatin (EZE/SIMV and rosuvastatin (ROSUV on oxidative stress (OS markers in patients with diabetic polyneuropathy (DPN. Methods. We performed a randomized, double-blind, placebo-controlled phase III clinical trial in adult patients with Type 2 Diabetes Mellitus (T2DM and DPN, as evaluated by composite scores and nerve conduction studies (NCS. Seventy-four subjects with T2DM were allocated 1 : 1 : 1 to placebo, EZE/SIMV 10/20 mg, or ROSUV 20 mg for 16 weeks. All patients were assessed before and after treatment: primary outcomes were lipid peroxidation (LPO, and nitric oxide (NO surrogate levels in plasma; secondary outcomes included NCS, neuropathic symptom scores, and metabolic parameters. Data were expressed as mean ± SD or SEM, frequencies, and percentages; we used nonparametric analysis. Results. LPO levels were reduced in both statin arms after 16 weeks of treatment (p<0.05 versus baseline, without changes in the placebo group. NO levels were not significantly affected by statin treatment, although a trend towards significance concerning increased NO levels was noted in both statin arms. No significant changes were observed for the NCS or composite scores. Discussion. EZE/SIMV and ROSUV are superior to placebo in reducing LPO in subjects with T2DM suffering from polyneuropathy. This trial is registered with NCT02129231.

    Full Text Available Subjective memory complaints (SMCs are common in older adults that can often predict further cognitive impairment. No proven effective agents are available for SMCs. The effect of BrainPower Advanced, a dietary supplement consisting of herbal extracts, nutrients, and vitamins, was evaluated in 98 volunteers with SMCs, averaging 67 years of age (47–88, in a randomized, double-blind, placebo-controlled trial. Subjective hypomnesis/memory loss (SML and attention/concentration deficits (SAD were evaluated before and after 12-week supplementation of BrainPower Advanced capsules (n=47 or placebo (n=51, using a 5-point memory questionnaire (1 = no/slight, 5 = severe. Objective memory function was evaluated using 3 subtests of visual/audio memory, abstraction, and memory recall that gave a combined total score. The BrainPower Advanced group had more cases of severe SML (severity ⩾ 3 (44/47 and severe SAD (43/47 than the placebo group (39/51 and 37/51, < 0.05, < 0.05, resp. before the treatment.

    Full Text Available OBJECTIVE: To assess the effects of carvedilol in patients with idiopathic dilated cardiomyopathy. METHODS: In a double-blind randomized placebo-controlled study, 30 patients (7 women with functional class II and III heart failure were assessed. Their ages ranged from 28 to 66 years (mean of 43±9 years, and their left ventricular ejection fraction varied from 8% to 35%. Carvedilol was added to the usual therapy of 20 patients; placebo was added to the usual therapy of 10 patients. The initial dose of carvedilol was 12.5 mg, which was increased weekly until it reached 75 mg/day, according to the patient's tolerance. Clinical assessment, electrocardiogram, echocardiogram, and radionuclide ventriculography were performed in the pretreatment phase, being repeated after 2 and 6 months of medication use. RESULTS: A reduction in heart rate (p=0.016 as well as an increase in left ventricular shortening fraction (p=0.02 and in left ventricular ejection fraction (p=0.017 occurred in the group using carvedilol as compared with that using placebo. CONCLUSION: Carvedilol added to the usual therapy for heart failure resulted in better heart function.

    The present study investigated the effects of repeated administration of Korodin(®), a combination of camphor and crataegus berry extract, on blood pressure and attentional functioning. This study was conducted based on a randomized, placebo-controlled, double-blind design. 54 persons participated (33 female, 21 male) with a mean age of 24.3 years. Blood pressure and body mass index were in the normal range. Participants received 20 drops of either Korodin(®) or a placebo for four times with interjacent time intervals of about 10 min. Blood pressure was measured sphygmomanometrically before and after each administration. Attentional performance was quantified by using two paper-and-pencil tests, the d2 Test of Attention and Digit Symbol Test. Greater increases in blood pressure occurred after the four Korodin(®) administrations in comparison to the four placebo administrations. The performance in two parameters of d2 Test of Attention was consistently superior after the intake of Korodin(®). The excellent tolerability and safety of Korodin(®), even after a total consumption of 80 drops, was confirmed. Copyright © 2014 Elsevier GmbH. All rights reserved.

    Hyperlipidemia is a common metabolic disorder contributing to morbidities and mortalities due to cardiovascular and cerebrovascular diseases. Conventional antihyperlipidemic drugs have limited efficacies and important side effects, so that alternative lipid lowering agents are needed. Salvia officinalis L. (sage) leaves have PPAR γ agonistic, pancreatic lipase and lipid absorption inhibitory, antioxidant, lipid peroxidation inhibitory and antiinflammatory effects. Thus, in this randomized double-blind placebo-controlled clinical trial with 67 hyperlipidemic (hypercholesterolemic and/or hypertriglyceridemic) patients aged 56.4 ± 30.3 years (mean ± SD), the effects of taking sage leaf extract (one 500 mg capsule every 8 h for 2 months) on fasting blood levels of lipids, creatinine and liver enzymes including SGOT and SGPT were evaluated in 34 patients and compared with the placebo group (n = 33). The extract lowered the blood levels of total cholesterol (p  0.05) compared with the placebo group at the endpoint. No adverse effects were reported. The results suggest that sage may be effective and safe in the treatment of hyperlipidemia.

    A randomized, double-blind, placebo-controlled clinical trial was conducted to evaluate the safety, reactogenicity and the immunogenicity of a 2 x 10(9)CFU dose of the 638 lyophilized live attenuated cholera vaccine for oral administration, formulated and produced at Finlay Institute, City of Havana, Cuba. Thirty-six healthy female and male adult volunteers from 18 to 40 years old were involved, clinically examined and laboratory tested after the informed consent signature. Adverse events were monitored and seroconversion rates and geometrical mean titer (GMT) of vibriocidal antibodies were tested in volunteer's sera samples. Neither serious adverse events nor other damages to the volunteers due to vaccine or placebo feeding were reported during the clinical follow-up period of this study; none of the adverse events registered within the first 72 h after inoculation were life-threatening for volunteers. Neither severe nor moderate adverse events were reported. Sixty-one percent of subjects showed mild expected adverse events in an interval lower than 24h up to the first 72 h, 75% of these in the vaccinated group and 18% in the placebo group. Fourteen days after inoculation the GMT of vibriocidal antibodies in the vaccine group significantly increased in comparison to the placebo group. All subjects in the vaccine group (24) seroconverted (100%). Results show that this vaccine is safe, well tolerated and immunogenic in healthy female and male volunteers.

    Iloprost has been reported to reduce Raynaud`s phenomenon (RP) and to inhibit progression of systemic sclerosis (SSc). The aim of our study was to compare monthly iloprost infusions with placebo in patients treated long-term. Seventeen patients, six with RP and 11 with SSc on monthly treatment with iloprost, received either a 3-hour intravenous infusion of iloprost or an equal volume of placebo once per month for 4 months in a monocentric, randomized, placebo-controlled, double-blind study. Raynaud attacks as measured by diary entries, skin temperature, skin sclerosis, fist closure, mouth opening, and digital ulcers were recorded during the observation period. Whereas mouth opening improved significantly (p = 0.043) in the iloprost-treated group, RS improved in both patient groups. However, no significant differences were found in the outcome measures. Although iloprost influences the inflammatory cascade in SSc, no statistical differences were seen in our study, indicating that treatment strategies with iloprost should be modified.

    Full Text Available Abstract Background Gum Arabic (acacia Senegal is a complex polysaccharide indigestible to both humans and animals. It has been considered as a safe dietary fiber by the United States, Food and Drug Administration (FDA since the 1970s. Although its effects were extensively studied in animals, there is paucity of data regarding its quantified use in humans. This study was conducted to determine effects of regular Gum Arabic (GA ingestion on body mass index and body fat percentage among healthy adult females. Methods A two-arm randomized, placebo controlled, double-blind trial was conducted in the Department of Physiology at the Khartoum University. A total of 120 healthy females completed the study. They were divided to two groups: A test group of 60 volunteers receiving GA (30 gm /day for 6 weeks and a placebo group of 60 volunteers receiving pectin (1 gm/day for the same period of time. Weight and height were measured before and after intervention using standardized height and weight scales. Skin fold thickness was measured using Harpenden Skin fold caliper. Fat percentage was calculated using Jackson and Pollock 7 caliper method and Siri equation. Results Pre and post analysis among the study group showed significant reduction in BMI by 0.32 (95% CI: 0.17 to 0.47; P Conclusions GA ingestion causes significant reduction in BMI and body fat percentage among healthy adult females. The effect could be exploited in the treatment of obesity.

To evaluate and predict the therapeutic efficacy of Fuzheng-Huayu tablet (FZHY based traditional Chinese Medicine (TCM syndrome differentiation or TCM symptoms on chronic hepatitis B caused cirrhosis (HBC. Methods. The trial was designed according to CONSORT statement. It was a multi-center, double-blind, randomized, placebo-controlled trail. Several clinical parameters, Child-Pugh classification and TCM symptoms were detected and evaluated. The FZHY efficacy was predicted by an established Bayes forecasting method following the Bayes classification model. Results. The levels of HA and TCM syndrome score in FZHY group were significantly decreased (P<0.05 compared to placebo group, respectively. The efficacy of FZHY on TCM syndrome score in HBC patients with some TCM syndromes was better. In TCM syndrome score evaluation, there were 53 effective and 22 invalid in FZHY group. TCM symptoms predicted FZHY efficacy on HBC were close to Child-Pugh score prediction. Conclusion. FZHY decreases the levels of HA and TCM syndrome scores, improves the life quality of HBC patients. Moreover, there were different therapeutic efficacies among different TCM syndromes, indicating that accurate TCM syndrome differentiation might guide the better TCM treatment. Furthermore, the FZHY efficacy was able to predict by Bayes forecasting method through the alteration of TCM symptoms.

    Uric acid has been linked with increased risk of chronic disease such as cardiovascular disease and this association has been attributed to a pro-inflammatory effect. Indeed, observational studies have shown that high uric acid is associated with high level of pro-inflammatory cytokines in the blood. However, whether high uric acid directly affects inflammation or rather represents a parallel defensive antioxidant mechanism in response to pathology that causes inflammation is unknown. To determine whether acute increase or decrease uric acid levels affects inflammation in healthy individuals, a randomized, placebo-controlled, double blind clinical study of uric acid or rasburicase with 20 healthy volunteers in each treatment-placebo group was conducted at the National Institute on Aging (NIA) Clinical Research Unit (CRU) at Harbor Hospital in Baltimore, MD. Change in inflammatory response was assessed by administering an oral lipid tolerance before and after the treatment of uric acid, rasburicase and placebo. Following uric acid administration, there was an accentuated increase in IL-6 during the oral lipid tolerance test (Puric acid with rasburicase. No side effects were reported throughout the trial. In health individuals, acute increase in uric acid results in an increased IL-6 response when challenged with lipid load. Such effect of amplification of inflammatory response may explain the higher risk of chronic diseases observed in subclinical hyperuricemia in observational studies. ClinicalTrials.gov NCT01323335.

    Chronic stress has been associated with a number of illnesses, including obesity. Ashwagandha is a well-known adaptogen and known for reducing stress and anxiety in humans. The objective of this study was to evaluate the safety and efficacy of a standardized root extract of Ashwagandha through a double-blind, randomized, placebo-controlled trial. A total of 52 subjects under chronic stress received either Ashwagandha (300 mg) or placebo twice daily. Primary efficacy measures were Perceived Stress Scale and Food Cravings Questionnaire. Secondary efficacy measures were Oxford Happiness Questionnaire, Three-Factor Eating Questionnaire, serum cortisol, body weight, and body mass index. Each subject was assessed at the start and at 4 and 8 weeks. The treatment with Ashwagandha resulted in significant improvements in primary and secondary measures. Also, the extract was found to be safe and tolerable. The outcome of this study suggests that Ashwagandha root extract can be used for body weight management in adults under chronic stress. © The Author(s) 2016.

Elderberries have been used traditionally, and in some observational and clinical studies, as supportive agents against the common cold and influenza. This randomized, double-blind placebo-controlled clinical trial of 312 economy class passengers travelling from Australia to an overseas destination aimed to investigate if a standardised membrane filtered elderberry (Sambucus nigra L. extract has beneficial effects on physical, especially respiratory, and mental health. Cold episodes, cold duration and symptoms were noted in a daily diary and assessed using the Jackson score. Participants also completed three surveys containing questions regarding upper respiratory symptoms (WURSS-21 and quality of life (SF-12 at baseline, just before travel and at 4-days after travel. Most cold episodes occurred in the placebo group (17 vs. 12, however the difference was not significant (p = 0.4. Placebo group participants had a significantly longer duration of cold episode days (117 vs. 57, p = 0.02 and the average symptom score over these days was also significantly higher (583 vs. 247, p = 0.05. These data suggest a significant reduction of cold duration and severity in air travelers. More research is warranted to confirm this effect and to evaluate elderberry’s physical and mental health benefits.

    Vaginal dryness is a common problem for which effective and safe nonestrogenic treatments are needed. Based on preliminary promising data that pilocarpine attenuated vaginal dryness, the current trial was conducted. A double-blind, placebo-controlled, randomized trial design was used to compare pilocarpine, at target doses of 5 mg twice daily and 5 mg four times daily, with a placebo. Vaginal dryness was recorded by patient-completed questionnaires at baseline and weekly for 6 weeks after study initiation. The primary endpoint for this study was the area under the curve summary statistic composed of the longitudinal responses obtained at baseline and through the 6 weeks of treatment to a numerical analogue scale asking patients to rate their perceived amount of vaginal dryness. The primary analysis was carried out by a single t test using a two-side alternative to compare the collective pilocarpine treatment arms with the collective placebo arms. A total of 201 patients enrolled in this trial. The primary analysis, comparing vaginal dryness symptoms in the collective pilocarpine arms against the placebo arm, did not reveal any benefit for the pilocarpine treatment. This finding was confirmed by other secondary analyses. Toxicity evaluation revealed more nausea, sweating, rigors, and urinary frequency with the pilocarpine arms compared with the placebo arm.

    Full Text Available Abstract Background Multilevel spinal fusion surgery has typically been associated with significant blood loss. To limit both the need for transfusions and co-morbidities associated with blood loss, the use of anti-fibrinolytic agents has been proposed. While there is some literature comparing the effectiveness of tranexamic acid (TXA to epsilon aminocaproic acid (EACA in cardiac procedures, there is currently no literature directly comparing TXA to EACA in orthopedic surgery. Methods/Design Here we propose a prospective, randomized, double-blinded control study evaluating the effects of TXA, EACA, and placebo for treatment of adolescent idiopathic scoliosis (AIS, neuromuscular scoliosis (NMS, and adult deformity (AD via corrective spinal surgery. Efficacy will be determined by intraoperative and postoperative blood loss. Other clinical outcomes that will be compared include transfusion rates, preoperative and postoperative hemodynamic values, and length of hospital stay after the procedure. Discussion The primary goal of the study is to determine perioperative blood loss as a measure of the efficacy of TXA, EACA, and placebo. Based on current literature and the mechanism by which the medications act, we hypothesize that TXA will be more effective at reducing blood loss than EACA or placebo and result in improved patient outcomes.

    Objectives Animal studies have demonstrated a role for substance P binding to neurokinin-1 receptor in the pathogenesis of acute pancreatitis. Our aim was to assess the efficacy of a neurokinin-1 receptor antagonist (aprepitant) at preventing post-ERCP pancreatitis in high risk patients. Methods Randomized, double-blind, placebo controlled trial at a single academic medical center. Patients at high risk for post-ERCP pancreatitis received either placebo or oral aprepitant administered 4 hours prior to ERCP, 80 mg 24 hours after the first dose, and then 80 mg 24 hours after the second dose. Fisher's exact test was used to compare incidence of post-ERCP pancreatitis in the two groups. Results 34 patients received aprepitant and 39 patients received placebo. Baseline characteristics were similar between the two groups. Incidence of acute pancreatitis was 7 in the aprepitant group and 7 in the placebo group. Hospitalization within 7 days post-procedure for abdominal pain that did not meet criteria for acute pancreatitis occurred in 6 and 9 patients in the aprepitant and placebo groups respectively (p=0.77). Conclusions Aprepitant did not lower incidence of post-ERCP pancreatitis in this preliminary human study. Larger studies potentially using the recently available intravenous formulation are necessary to conclusively clarify the efficacy of aprepitant in this setting. PMID:22964958

    The objective of the study was to assess the efficacy and safety of desvenlafaxine (administered as desvenlafaxine succinate) for the treatment of vasomotor symptoms. This was a 26 week, double-blind, placebo-controlled trial of 567 postmenopausal women (mean age, 53.7 years; time since natural menopause, 4.8 years) experiencing 50 or more hot flushes (HFs) per week, randomly assigned to desvenlafaxine (100 or 150 mg) or placebo. Change from baseline in average daily number of moderate to severe HFs and average daily HF severity were compared with placebo at weeks 4, 12, and 26. A significantly greater decrease from baseline in number of HFs occurred at weeks 4 and 12 with 100 and 150 mg desvenlafaxine compared with placebo (week 12 reductions: 60%, 66%, and 47%, respectively; all P desvenlafaxine compared with placebo (all P desvenlafaxine-treated subjects than placebo-treated subjects discontinued because of adverse events during week 1 only. Desvenlafaxine is an effective treatment for menopausal HFs.

    Full Text Available "n "nBackground and the purpose of the study: Diabetes mellitus is one of the most common chronic diseases in the world with dreadful complications which not only is debilating for the patients but also puts a big burden on the health system.One of the mechanisms by which the complications of diabetes occur is imbalance in the oxidant-antioxidant equilibrium in the body and therefore many studies have been performed to either correct this equilibrium or delay the occurrence of the complications. "nMethods:In this randomized, double-blind placebo-controlled clinical trial, a total number of 61 subjects were divided into two groups and the antioxidant effects of a novel herbal drug, Semelil,was compared with placebo. Baseline laboratory tests including a complete blood count, fasting blood sugar,lipid profile,fasting plasma insulin, liver and renal function tests plus tumor necrotizing factor α (TNFα and C-reactive protein (CRP and homocystein were performed. Total antioxidant power assay, cellular lipid peroxidation assay, and nuclear damage (deoxyguanosine and carbonly molecules were also measured to help determination of state of antioxidants- oxidants equilibrium in serum. "nResult:Apart from deoxyguanosine, no significant change was found in TNFα or CRP levels in the studied group who received Semelil.Conclusion: Mechanisms other than antioxidant effects are involved for Semelil in the treatment of diabetic foot ulcers.

    Tonsillectomy using a KTP laser has been performed increasingly but is not a routinely practised technique in the UK. In the USA, tonsillectomy is often performed as a day case procedure but, here in the UK, it is still standard practice to admit patients for overnight stay. We present the largest prospective double-blind randomized controlled trial to date (151 patients) comparing KTP laser with standard dissection tonsillectomy and assess the suitability of both procedures for day case surgery. We found that there was significantly less peroperative haemorrhage if tonsillectomy was performed using the KTP laser, but it did cause more postoperative pain, more depression in mood and a higher rate of both reactionary and secondary haemorrhage, which was not significant when compared with conventional dissection. There was no difference in operating time, and over 40% of patients in each group needed overnight admission. We conclude that KTP laser tonsillectomy offers no benefit apart from less intraoperative bleeding over standard dissection tonsillectomy. Discharge from hospital after tonsillectomy was found to be unpredictable. Tonsillectomy is therefore an unsuitable procedure for planned surgery through a day unit, but approximately 58% of patients could be discharged on the same day from an extended day surgery unit, and the rest have one night in hospital.

    Diazepam is one of the most widely used, broad-spectrum anti-anxiety agents. The aim of this study was to evaluate the efficacy of diazepam, and to establish whether it is more effective than a placebo in improving the various neurotic anxiety states seen in patients with neurosis or psychosomatic disease. Of the recently established comprehensive register of psychotropic drug trials carried out in Japan, a total of 17 double-blind, randomized controlled trials were identified on the treatment of neurosis using anti-anxiety compounds, in which both diazepam and placebos were used. Meta-analysis of these 17 studies demonstrated that diazepam is significantly more effective than a placebo (relative risk 1.35, 95% confidence interval 1.21-1.51, number needed to treat 9). The maximal effective dose of diazepam seems to be 12 or 18 mg/day with a treatment duration of 2 or more weeks. There was no significant difference between the effects of placebo and a diazepam dose of 6 mg/day. Caution should be exercised in assessing these results, however, since this is the first meta-analysis showing the significant effectiveness of diazepam in the treatment of neurosis or psychosomatic disease.

    Some studies have demonstrated the beneficial effects of Spirulina maxima (Arthrospira maxima) consumption on glycemic, lipid, and blood pressure parameters. The aim of this study was to investigate the effect of Spirulina maxima on body weight, blood pressure, and endothelial function. In this randomized double-blind placebo-controlled trial, 40 patients with hypertension but lacking evidence of cardiovascular disease were enrolled to receive daily either 2.0 g Hawaiian spirulina or placebo for three months. Anthropometric parameters, systolic blood pressure (SBP), diastolic blood pressure (DBP), and stiffness index (SI) using digital plethysmography were measured before and after the intervention. After three months, there was no change in body mass index (BMI) or weight in either the spirulina or the placebo group. However, a significant reduction in SBP and SI was observed. The patients in the spirulina group showed significant reductions in BMI (26.9 ± 3.1 vs. 25.0 ± 2.7 kg/m(2), p = 0.0032), weight (75.5 ± 11.8 vs. 70.5 ± 10.3 kg, p Spirulina maxima not only improves BMI and weight but also results in improvements in blood pressure and endothelial function spirulina in overweight patients with hypertension but lacking evidence of cardiovascular disease.

    These are the first prospective studies to use criteria for menstrual migraine proposed in the 2004 revision of the International Classification of Headache Disorders (ICHD-II) to examine the efficacy of rizatriptan for treatment of a menstrual attack. Two identical protocols (MM1 and MM2) were randomized, parallel, placebo-controlled, double-blind studies. Adult women with ICHD-II menstrual migraine were assigned to either rizatriptan 10-mg tablet or placebo in a 2 : 1 ratio. Patients treated a single menstrual migraine attack of moderate or severe pain intensity. The primary end-point was 2-h pain relief and the secondary end-point was 24-h sustained pain relief. A total of 707 patients (MM1 357, MM2 350) treated a menstrual migraine attack. The percentage of patients reporting 2-h pain relief was significantly greater for rizatriptan than for placebo (MM1 70% vs. 53%, MM2 73% vs. 50%), as was the percentage of patients reporting 24-h sustained pain relief (MM1 46% vs. 33%; MM2 46% vs. 33%). Rizatriptan 10 mg was effective for the treatment of ICHD-II menstrual migraine, as measured by 2-h pain relief and 24-h sustained pain relief.

    Skin cancer is an increasing problem in modern dermatology. Earlier studies have shown protective effects against ultraviolet radiation (UVR)-induced skin damage by topical treatment with melatonin. However, the potential sedative effects of full body topical application of melatonin have never been investigated. Objectives The aim of this study was to assess the degree of cognitive dysfunction when using melatonin cream as full body topical application. In a randomized, placebo-controlled, double-blind crossover study in healthy volunteers, the degree of cognitive dysfunction when using cream containing 12.5% melatonin as full body application was assessed. A group of ten volunteers had melatonin cream 12.5% applied on 80% of their body surface area, and degree of cognitive dysfunction was assessed using a test battery consisting of Karolinska sleepiness scale (KSS), Finger tapping test (FTT) and Continuous Reaction time (CRT). No significant effects on cognitive parameters were found. However, great inter-individual variations on cognitive parameters were observed. This study was the first to assess degree of cognitive dysfunction resulting from application of melatonin cream on a full body surface area. The results support that melatonin is a safe drug for dermal application even in a high dosage.

    Male pattern baldness, or androgenetic alopecia, affects approximately 50% of the adult population and can cause poor self-image, low self-esteem and have a significant negative impact on the quality of life. An oral nutraceutical supplement based on a marine complex formulation has previously been reported to significantly increase the number of terminal hairs in women with thinning hair. The objective of this double-blind, placebo-controlled study was to confirm the beneficial effects of a similar marine complex supplement in adult male subjects with thinning hair (Viviscal(®) Man; Lifes2good, Inc., Chicago, IL, USA). Healthy adult male subjects with thinning hair associated with clinically diagnosed male pattern hair loss were enrolled and randomized to receive study drug or placebo twice daily. At Day 90, subjects indicated a significant improvement in three of six quality of life measures as well as a significant overall improvement in quality of life. After 180 days, significant increases were observed for total hair count, total hair density, and terminal hair density (for each, P = 0.001). The investigator assessments revealed significant improvements in terminal and vellus hair count and terminal hair density. Hair pull test results were significantly lower (fewer hairs removed) for study drug vs. placebo at Days 90 (P hair shedding and promote hair growth in men with thinning hair. © 2016 Wiley Periodicals, Inc.

    Full Text Available Abstract Background There are no published studies that have compared bronchodilatory effect of inhaled budesonide/formoterol combination with budesonide/salbutamol delivered by metered dose inhaler with a spacer in acute exacerbation of asthma in children. We, therefore, compared the bronchodilatory effects of inhaled budesonide/formoterol (dose: 200 μg and 12 μg respectively combination with budesonide (200 μg/salbutamol (200 μg administered by metered dose inhaler and spacer in children of 5-15 years with mild acute exacerbation of asthma [Modified Pulmonary Index Score (MPIS between 6-8] in this double-blind, randomized controlled trial. The primary outcome was FEV1 (% predicted in the two groups at 1, 5, 15, 30, 60 min after administration of the study drug. Results We did not observe any significant differences in the % predicted FEV1 and MPIS between formoterol and salbutamol at various time points from 1 min to 60 min post drug administration. There was significant improvement in FEV1 (% predicted from baseline in both the groups as early as 1 min after drug administration. Conclusions Salbutamol or formoterol delivered along with inhaled corticosteroid by metered dose inhaler with spacer in children between 5-15 years of age with mild acute exacerbation of asthma had similar bronchodilatory effects.

    Full Text Available Infrared (IR therapy is used for pain relief in patients with knee osteoarthritis (OA. However, IR’s effects on the cardiovascular system remain uncertain. Therefore, we investigated the local and systemic cardiovascular effects of monochromatic IR therapy on patients with knee OA in a double-blind, randomized, placebo-controlled study. Seventy-one subjects with knee OA received one session of 40 min of active or placebo monochromatic IR treatment (with power output of 6.24 W, wavelength of 890 nm, power density of 34.7 mW/cm2 for 40 min, total energy of 41.6 J/cm2 per knee per session over the knee joints. Heart rate, blood pressure, and knee arterial blood flow velocity were periodically assessed at the baseline, during, and after treatment. Data were analyzed by repeated-measure analysis of covariance. Compared to baseline, there were no statistically significant group x time interaction effects between the 2 groups for heart rate (P=0.160, blood pressure (systolic blood pressure: P=0.861; diastolic blood pressure: P=0.757, or mean arterial blood flow velocity (P=0.769 in follow-up assessments. The present study revealed that although there was no increase of knee arterial blood flow velocity, monochromatic IR therapy produced no detrimental systemic cardiovascular effects.

    We evaluated the efficacy and safety of three doses of a novel alprostadil cream in a randomized, double-blind, placebo-controlled study in 94 women presenting with female sexual arousal disorder of at least 6 month s duration. We sent the subjects home with 10 premeasured doses of 500 g, 1000 g, or 1500 g alprostadil or a placebo cream to be applied to the vulvar area prior to vaginal intercourse over a period of 6 weeks. The primary efficacy parameter, the arousal success rate (as measured by diary responses to the Female Sexual Encounter Profile [FSEP]), was highest in the alprostadil 1000 g group and lowest in the 500 g group, but the responses were not different from that of the placebo cream, at the p = 0.05 level, for any of the three alprostadil doses. However, the change from baseline for Item 6 of the Female Sexual Function Index (FSFI; Rosen et al., 2000; satisfaction with arousal during sexual activity) suggested an important dose-related trend (p = 0.173; 1500 g versus placebo). The mean percent responder rate (responder = > 50% arousal success rate with > 3 sexual attempts) suggested a dose-response effect (p = 0.157; 1500 g versus placebo). Adverse events were generally mild or moderate in intensity and mainly involved localized reactions in the genital area.

    The objective of this study was to evaluate the efficacy, safety and tolerability of brexpiprazole versus placebo in adults with acute schizophrenia. This was a 6-week, multicenter, placebo-controlled double-blind phase 3 study. Patients with acute schizophrenia were randomized to brexpiprazole 1, 2 or 4 mg, or placebo (2:3:3:3) once daily. The primary endpoint was changed from baseline at week 6 in Positive and Negative Syndrome Scale (PANSS) total score; the key secondary endpoint was Clinical Global Impressions-Severity (CGI-S) at week 6. Brexpiprazole 4 mg showed statistically significant improvement versus placebo (treatment difference: -6.47, p=0.0022) for the primary endpoint. Improvement compared with placebo was also seen for the key secondary endpoint (treatment difference: -0.38, p=0.0015), and on multiple secondary efficacy outcomes. Brexpiprazole 1 and 2mg also showed numerical improvements versus placebo, although p>0.05. The most common treatment-emergent adverse events were headache, insomnia and agitation; incidences of akathisia were lower in the brexpiprazole treatment groups (4.2%-6.5%) versus placebo (7.1%). Brexpiprazole treatment was associated with moderate weight gain at week 6 (1.23-1.89 kg versus 0.35 kg for placebo); there were no clinically relevant changes in laboratory parameters and vital signs. In conclusion, brexpiprazole 4 mg is an efficacious and well-tolerated treatment for acute schizophrenia in adults. Clinical Trials.gov NCT01393613; BEACON trial.

    Full Text Available Pumpkin seed oil (PSO has been shown to block the action of 5-alpha reductase and to have antiandrogenic effects on rats. This randomized, placebo-controlled, double-blind study was designed to investigate the efficacy and tolerability of PSO for treatment of hair growth in male patients with mild to moderate androgenetic alopecia (AGA. 76 male patients with AGA received 400 mg of PSO per day or a placebo for 24 weeks. Change over time in scalp hair growth was evaluated by four outcomes: assessment of standardized clinical photographs by a blinded investigator; patient self-assessment scores; scalp hair thickness; and scalp hair counts. Reports of adverse events were collected throughout the study. After 24 weeks of treatment, self-rated improvement score and self-rated satisfaction scores in the PSO-treated group were higher than in the placebo group (P = 0.013, 0.003. The PSO-treated group had more hair after treatment than at baseline, compared to the placebo group (P<0.001. Mean hair count increases of 40% were observed in PSO-treated men at 24 weeks, whereas increases of 10% were observed in placebo-treated men (P<0.001. Adverse effects were not different in the two groups.

    To investigate the combined effect of transcranial direct current stimulation (tDCS) and home-based occupational therapy on activities of daily living (ADL) and grip strength, in patients with upper limb motor impairment following intracerebral hemorrhage (ICH). A double-blind randomized controlled trial with one-week follow-up. Patients received five consecutive days of occupational therapy at home, combined with either anodal (n = 8) or sham (n = 7) tDCS. The primary outcome was ADL performance, which was assessed with the Jebsen-Taylor test (JTT). Both groups improved JTT over time (p occupational therapy provided greater improvements in grip strength compared with occupational therapy alone. tDCS is a promising add-on intervention regarding training of upper limb motor impairment. It is well tolerated by patients and can easily be applied for home-based training. Larger studies with long-term follow-up are needed to further explore possible effects of tDCS in patients with ICH. Five consecutive days of tDCS combined with occupational therapy provided greater improvements in grip strength compared with occupational therapy alone. tDCS is well tolerated by patients and can easily be applied for home-based rehabilitation.

    Previous studies have shown improvement in patellar tendinopathy symptoms after platelet-rich plasma (PRP) injections, but no randomized controlled trial has compared PRP with dry needling (DN) for this condition. To compare clinical outcomes in patellar tendinopathy after a single ultrasound-guided, leukocyte-rich PRP injection versus DN. Randomized controlled trial; Level of evidence, 1. A total of 23 patients with patellar tendinopathy on examination and MRI who had failed nonoperative treatment were enrolled and randomized to receive ultrasound-guided DN alone (DN group; n = 13) or with injection of leukocyte-rich PRP (PRP group; n = 10), along with standardized eccentric exercises. Patients and the physician providing follow-up care were blinded. Participants completed patient-reported outcome surveys before and at 3, 6, 9, 12, and ≥26 weeks after treatment during follow-up visits. The primary outcome measure was the Victorian Institute of Sports Assessment (VISA) score for patellar tendinopathy at 12 weeks, and secondary measures included the visual analog scale (VAS) for pain, Tegner activity scale, Lysholm knee scale, and Short Form (SF-12) questionnaire at 12 and ≥26 weeks. Results were analyzed using 2-tailed paired and unpaired t tests. Patients who were dissatisfied at 12 weeks were allowed to cross over into a separate unblinded arm. At 12 weeks after treatment, VISA scores imp
